Patent
Segetis Inc. | Date: 2015-01-30

The present invention is directed to formulations including a polymer and a plasticizer composition. The plasticizer composition is a blend of an alkyl ketal ester plasticizer and a second plasticizer selected from a cycloaliphatic compound, an ortho phthalate compound, a terephthalate compound, a benzoate ester compound, and a bio-based compound. The plasticizer composition is at least 10% by weight of the total of the polymer and the plasticizer composition.

Disclosed herein are ketal amide compounds. The ketal amide compounds are synthesized by the reaction of ketal acids or ketal esters with amine functional compounds. Also disclosed are methodologies useful to make the ketal amide compounds. Also disclosed herein are formulations and articles containing the ketal amide compounds.


A biocide composition comprises a biocide and an adjuvant comprising a ketal having the formula (1) wherein a is 0 or an integer of 1 to 12, specifically 1 to 6, more specifically 1 to 4, still more specifically 2 to 4; b is 0, 1, or 2; R is C(O)OR^(1 )or CH_(2)OH; R^(1 )is a C_(1-18 )alkyl or C_(5-8 )cycloaliphatic or heterocyclic group; R^(2 )is a divalent C_(1-8 )alkylene group optionally substituted with up to 5 hydroxyl groups; R^(3 )and R^(4 )are each independently hydrogen or C_(1-6 )alkyl; and R^(5 )is hydrogen or C_(1-3 )alkyl.


A crude composition comprising a ketocarboxylic acid such as levulinic acid, derived from biomass in an aqueous phase comprising impurities, can be efficiently converted in high yield to the corresponding dicarboxylic acid, such as succinic acid, which can be purified and dried.


A method for the manufacture of 1,8-octanedioic acid comprises: reacting gamma-valerolactone with an alcohol in the presence of an acid or a base catalyst to provide an alkyl pentenoate, converting the alkyl pentenoate in the presence of a metathesis initiator to provide the dialkyl octenedioate, reacting the dialkyl octenedioate with hydrogen in the presence of a hydrogenation catalyst to provide a dialkyl 1,8-octanedioate and hydrolyzing the dialkyl 1,8-octanedioate to provide the 1,8-octanedioic acid.

A ketal amide has a structure represented by formula (I): wherein R is hydrogen or C_(1-8 )alkyl; R^(1 )is substituted or unsubstituted, saturated or unsaturated C_(1-36 )alkyl, or an alkylene oxide of the formula (C_(n)H_(2n)O)_(p)C_(n)H_(2n)OR^(a )wherein n is 1-4, p is 1-1000 and R^(a )is H or C_(n)H_(2n+1 )wherein n is 1 to 4, R^(2 )is hydrogen or C_(1-3 )alkyl, each R^(3), R^(4), and R^(5 )is independently hydrogen or C_(1-6 )alkyl, R^(6 )is hydrogen or C_(1-6 )alkyl, R^(7 )is C_(1-6 )alkyl substituted with 1-4 hydroxyl groups, a is 0-3, and b is 0-1. Methods to prepare the ketal amide and compositions containing the ketal amide are also disclosed.

Patent
Segetis Inc. | Date: 2015-06-22

The present disclosure relates to the preparation of ketal compounds from polyols and oxocarboxylates, and uses thereof.


Personal care formulations containing alkyl ketal esters having the structure wherein a is 0 or an integer of 1 to 12; b is 0 or 1; R^(2 )is a divalent C_(1-8 )group optionally substituted with up to 5 hydroxyl groups; and R^(1 )is C_(1-6 )alkyl.


Disclosed herein is a polyhydroxy ketal adduct obtained by the esterification of a hydrocarbon polyol by at least 1.5 equivalents of a ketocarboxy to produce an intermediate ketocarboxylic ester. The intermediate polyketocarboxylic ester is then ketalized to produce the polyhydroxyketal adduct, which can be used to provide a polymeric composition.
