Disclosed is a mixed refrigerant having a GWP value less than 150. The mixed refrigerant consists of 2,3,3,3-tetra-fluoropropene (HFO-1234yf), Trans-1,3,3,3-tetra-fluoropropene (HFO-1234ze(E)) and trifluoromehyl ether(CH_(3)OCH_(3),HFE-143a), and the mass percent thereof is: HFO-1234yf: 52%-90%; HFO-1234ze(E): 5%-30%; HFE-143a: 5-18%. The mixed refrigerant t does not destroy atmosphere ozonosphere, the greenhouse effect value is very low, and the environmental protection performance is excellent; the thermal performance is equivalent to HFC-134a. It can be directly used in the system originally using the existing HFC-134a without changing any details to achieve the filling replacement, enhancing energy efficiency ratio and reducing filling capacity. It has the advantage of low replacement cost, resource economization. It can be used as a long substitute for HFC-134a in the automotive air conditioner.


The present invention relates to the preparation of -lactam antibodies comprising contacting 4-hydroxyphenylglycine of phenylglycine, cysteine and valine with a non-ribosomal peptide synthetase and subsequent cyclization using an isopenicillin N synthase in the presence of an MbtH-like protein and to a host cell equipped to perform such preparation.

Disclosed is a preparation method for perfluoro-2-methyl-3-pentanone. In the presence of fluoride salts and ether compounds, perfluoro-2, 3-epoxide-2-methyl pentane is converted into perfluoro-2-methyl-3-pentanone by a catalytic rearrangement reaction, which has characteristics such as mild action condition, fast reaction rate, high reaction selectivity and high yield. The prepared perfluoro-2-methyl-3-pentanone can be used as detergent, solvent and extinguishant. The perfluoro-2, 3-epoxide-2-methyl pentane is prepared by using perfluoro-2-methyl-2-amylene as raw material to react with sodium hypochlorite, and the perfluoro-2-methyl-2-amylene raw material is prepared through the catalytic isomerization reaction by using perfluoro-4-methyl-2-amylene as raw material.
