A process to form a composition comprising an asymmetrical polyene, the asymmetrical polyene comprising an '&#x3b1;,&#x3b2; unsaturated-carbonyl end' and a 'C&#x2014;C double bond end,' the process comprising: reacting an alkene- or polyene-containing alcohol with an alkyl ester of an &#x3b1;,&#x3b2; unsaturated carboxylic acid in the presence of at least the following components A) through C) to form a solution comprising an asymmetrical polyene: A) a lithium salt; B) a component selected from the group consisting of hydroquinone, an alkyl-substituted phenol, a substituted alkyl-substituted phenol, an alkyl-substituted hydroquinone, a substituted alkyl-substituted hydroquinone, and combinations thereof; and C) an N-oxyl-containing compound; wherein the &#x201c;&#x3b1;,&#x3b2; unsaturated-carbonyl end&#x201d; of the asymmetrical polyene is selected from the group consisting of structures a) through c), as described herein, and wherein the &#x201c;C&#x2014;C double bond end&#x201d; of the asymmetrical polyene is selected from the group consisting of structures 1) through 17), as described herein.

Inhibitor combination for lithium salt-catalyzed transesterification process and method for removing lithium salt

Provided is a process for making (2-nitro)alkyl (meth)acrylate compounds of formula I: wherein n, R, R, R, R, R, R, R, and n are as defined herein, by a transesterification reaction between a nitroalcohol compound and a (meth)acrylate compound in the presence of a transesterification catalyst and a free radical inhibitor. 

Synthesis of (2-nitro)alkyl (meth)acrylates via transesterification of (meth)acrylate esters

A process comprising for preparing Cto Calkyl(meth)acrylates, such as butyl acrylate, wherein vaporized reactor contents are fed directly to a column, the aqueous reflux ratio to the column is from 4 to 12, and the level of acrylic acid in the primarily organic phase separated from the overhead condensate of the column is less than 2000 ppm.

Acrylate production process

The present invention relates to a process for providing improved low VOC polymerizable compositions containing phosphoalkyl (meth)acrylate monomers which are synthesized by the reaction of a hydroxyalkyl (meth)acrylate with polyphosphoric acid (PPA).

Polymerizable compositions

The present invention provides a method for minimizing the decomposition of cyanohydrins in exothermic chemical reactions involving cyanohydrins. The method comprises providing a reaction medium and reactants to a tubular reactor having internal mixing means, mixing the reaction medium and reactants to form a homogenous reaction mixture, removing heat from the reaction process and reacting the reactants to produce a mixed product having a bulk temperature. The method may further comprise cooling the reaction medium to a temperature from 1-10&#xb0; C. cooler than the bulk temperature of the mixed product prior to providing the reaction medium to the tubular reactor.

Process for chemical reactions involving cyanohydrins

A method of preparing a curable coating and a method of curing the curable coating are disclosed. The curable composition from which the curable coating is prepared may be applied to the surface of a substrate in neat form or in aqueous medium to produce the coating. Curing of the curable coating may be accomplished by chemical generation of free radicals, by electrochemical generation of free radicals, by electron beam, by photochemical generation of free radicals, or by other electromagnetic irradiation.
