International Classification:

C07C 67/26
C07C 69/587

Abstract:

The present invention is a process for preparing a hydroxyalkyl sorbate comprising the steps of of: a) contacting together in a reaction vessel a solvent, sorbic acid, a transition metal halide catalyst, an anti-oxidant, and an alkylene oxide under conditions sufficient to form the hydroxyalkyl sorbate; b) removing the solvent in vacuo, wherein the anti-oxidant is characterized by the following formula or a carboxylic acid salt thereof:wherein Y, x, and Rare defined herein. The process of the present invention provides a convenient way of preparing hydroxyalkyl sorbates in high yield and purity without complicated workup steps.

International Classification:

C07C 67/26
C07C 69/587
C07C 67/58

Abstract:

The present invention is a process for preparing a sorbate ester comprising the steps of: a) contacting together in a reaction vessel a first organic solvent, sorbic acid, a catalytic amount of TiC14, an anti-oxidant, and an alkylene oxide under conditions sufficient to form a mixture of the sorbate ester and residual water-soluble impurities; then b) separating the sorbate ester from the residual water-soluble impurities by washing. Sorbate esters can be prepared in an efficient and cost-effective manner by the process of the present invention.

International Classification:

C09D 7/12
C09D 133/00

Abstract:

The present invention is a composition comprising a stable aqueous dispersion of polymer particles and a sorbate ester, which is a liquid at 20 C. and has a molecular weight in the range of 125 to 500 g/mol. The composition of the present invention provides a way to enhance film formation of coatings prepared using relatively high Tlatexes without the aid of high volatile organic content (VOC) coalescents.

International Classification:

C09D 7/12
C09D 5/00

Abstract:

The present invention is a composition comprising a solution or a dispersion of polymer particles, a sorbate ester or sorbamide curing agent, and a cure modulating additive for the curing agent. The curing agent is a sorbic acid ester or a sorbamide and the cure modulating agent is a reagent capable of accelerating or attenuating the rate of cure of the curing agent. The control of cure kinetics is important for speeding up cure rates where rates are too slow or by reducing cure rates where curing too rapidly results in undesirable color formation.
