The liquefaction experiments were carried out using wheat straw as raw material, concentrated sulfuric acid as catalyst and ethanol as solvent. The composition of liquefied product was analyzed, and the effects of different conditions on conversion rate and yield of the target product ethyl levulinate (EL) were examined. The results showed that optimum liquefaction conditions was catalyst dosage 10%, reaction temperature 190℃, reaction time 60 min, and liquid solid ratio of 18∶1 (g∶g, the same below). Under the circumstances, the yield of EL was up to 18.11% with liquefaction ratio of 75%. Degradation of wheat straw during the reaction was confirmed by infrared spectroscopic analysis. The liquid product contained aldehydes, ketones, esters, phenols, acids, and some other oxygenates. It was found that cellulose was converted into intermediate, such as glucose, glucoside, ethoxymethyl furfural, et al. They can be further transformed into ethyl levulinate. © 2016, Editorial Board of «Chemistry and Industry of Forest Products». All right reserved.

The liquefaction of bamboo powder was investigated in ethanol-phenol under high pressure using H2SO4 as catalyst. The liquefaction conditions were optimized by response surface analysis and its result was analyzed using Design-Expert 8.0.6 software. The effects conditions were investigated by a five level three-factor Box-Behnken design. The results showed that the liquefaction rate reached 98.5% under the optimum conditions, i.e., mass ratio of phenol and bamboo powder 1:1, ethanol and bamboo powder 18:1, sulfuric acid amount 5%,reaction temperature 200℃ and reaction time 70 min.The product analysis showed that the bamboo powder could be effectively degraded in blended solvents. The FT-IR, SEM and TG results of residue indicated that the molecular structure of bamboo powder present significant change via liquefaction and the compounds with different substituent on aromatic ring were obtained. The GC-MS analysis showed that the oil produced by this way was complex in composition with some major compounds such as alcohols, phenols, ketones and esters, and the GC content of ethyl levulinate reached 10.11%. © 2016, Editorial Board of «Chemistry and Industry of Forest Products».

Three kinds of crops (wheat, corn and rice) straw were selected as raw materials for pressurized liquefaction. Ethanol and concentrated sulfuric acid (98%) were used as solvent and catalyst, respectively. The liquefaction was carried out under the conditions of reaction temperature 200℃, the dosage of catalyst 5%, the reaction time 60 min and the solid-liquid ratio 1:15. Products of liquefaction were analyzed, and ethyl levulinate (EL) was isolated from the liquefaction products. The results showed that under the same liquefaction conditions, wheat straw performed high liquefied performance. The structure of straw components was changed and degraded. Ethyl levulinate was the main component of liquefaction products. The purity and recovery rate of ethyl levulinate isolated by distillation were 92.71% and 89.93%, respectively. © 2016, Editorial Board of «Chemistry and Industry of Forest Products».

An epoxy oil-based fire-retardant plasticizer with a triazine ring structure (THEIC-SBOE) has been prepared by transesterification and epoxidation using tris(2-hydroxyethyl)isocyanurate and soybean oil methyl ester as the main raw materials. The structure of THEIC-SBOE has been characterized by FTIR, 1H NMR and 13C NMR spectroscopies and elemental analysis and its thermal stability has been measured by thermogravimetric analysis. Its epoxy value and acid value have been determined as 4.3 % and 0.6 mg KOH g-1, respectively. Examination of the morphology of carbon residue from PVC by scanning electron microscopy showed THEIC-SBOE to serve as an intumescent flame retardant. The results showed that, with the same plasticizer contents incorporated into PVC, THEIC-SBOE imparted similar mechanical properties as epoxidized soybean oil. Furthermore, PVC blends incorporating the synthesized plasticizer THEIC-SBOE displayed better fire-retardant properties than those incorporating dioctyl phthalate. The limiting oxygen index of such a PVC blend reached 28.4 % with 35 % (w/w) THEIC-SBOE incorporation.

An epoxy oil-based fire-retardant plasticiser with a triazine ring structure [tris(2-hydroxyethyl) isocyanurate-soybean oil emulsion (THEIC-SBOE)] has been prepared by transesterification and epoxidation using tris(2-hydroxyethyl) isocyanurate and soybean oil methyl ester as the main raw materials. The structure of THEIC-SBOE has been characterised by Fourier transform infrared, 1H-NMR and 13C-NMR spectroscopies and elemental analysis, and its thermal stability has been measured by thermogravimetric analysis. Its epoxy value and acid value have been determined as 4·3% and 0·60 mg·KOH g-1, respectively. Examination of the morphology of carbon residue from poly (vinyl chloride) by scanning electron microscopy showed THEIC-SBOE to serve as an intumescent flame retardant. The results showed that, with the same plasticiser contents incorporated into poly (vinyl chloride), THEIC-SBOE imparted similar mechanical properties as epoxidised soybean oil. Furthermore, poly (vinyl chloride) blends incorporating the synthesised plasticiser THEIC-SBOE displayed better fire-retardant properties than those incorporating dioctyl phthalate. The limiting oxygen index of such a poly (vinyl chloride) blend reached 28·4 with 35% (w/w) THEIC-SBOE incorporation. © W. S. Maney & Son Ltd 2015.

An epoxy oil-based plasticizer with a triazine ring structure (THEIC-ESBO) has been prepared using tris(2-hydroxyethyl) isocyanurate (THEIC) and soybean oil methyl ester as the main raw materials. The structure of THEIC-ESBO has been characterized by 1H NMR and 13C-NMR and elemental analysis. THEIC-ESBO substituting epoxy soybean oil (ESO) was used to plasticize PVC blends (PVC/THEIC-ESBO). when 60-70% ESO was substituted by THEIC-ESBO in PVC blends, the results of the mechanical properties and the dynamic thermomechanical analysis (DMA) indicate that plasticizing and compatibility of the plasticizer with PVC remained excellent, and the glass transition temperature (Tg) was 46.4°C. The thermal stability of PVC blends was investigated by thermogravimetric analysis (TGA). The Fire performance of the PVC/THEIC-ESBO was investigated by the limiting oxygen index (LOI) and cone calorimeter test. When THEIC-ESBO was used as plasticizers alone, the LOI of the PVC blend reached 26.1%. The cone calorimetric data show that with increasing THEIC-ESBO, the time to ignition prolong, the value of the heat release rate (HRR) and the total heat release (THR) were reduced, the total smoke of release (TSR) was increased, both of the release rate of CO and CO2 were increased, but the value of CO/CO2 was decreased, the value of the residual char yield (C-Y) was significantly enhanced. All the data indicated that flame retardant of PVC blends using THEIC-ESBO substitute ESO was significantly improved, and THEIC-ESBO exhibits flame inhibition in the gaseous phase. The mechanism of flame retardancy of PVC/THEIC-ESBO was investigated by pyrolysis gas chromatographymass spectrometry (Py-GC/MS). The results indicate that nitrogen-containing compounds from THEIC-ESBO pyrolysis dilute the concentration of combustible gases, the cross-linking reaction is also promoted the char yield. SO, during PVC blends combustion process, the flame retardant of PVC/THEIC-ESBO was enhanced. © 2015 Elsevier B.V.

In this paper, castor oil-based flame retardant polyols were synthesized using castor oil as raw material pretreated through glycerol alcoholysis, hydrogen peroxide epoxidation and ring-opening reaction between diethyl phosphate and epoxy group. The castor oil-based flame retardant polyols were than reacted with MDI to produce polyurethane foam (PUF). The structure of castor oil-based flame retardant polyols was characterized by FT-IR and 1H NMR. The mechanical behavior and flame resistance of PUF was studied by universal testing machine and limiting oxygen index (LOI) and thermogravimetric analysis, respectively. The results showed that the castor oil-based flame retardant polyols were prepared by a series of reactions and the hydroxyl value was increased to 420 mg/g. The value of PUF's LOI could reach about 23.8% from 20.1% compared with PUF prepared by alcoholisis castor oil, although the content of phosphorus in PUF is merely 1% and without any fire retardant. The compressive strength of polyurethane foam is increased from 0.118 MPa to 0.128 MPa and thermal stability of polyurethane foam increase with castor oil-based flame retardant polyols content increasing.
