Disclosed is a 4-step process for the preparation of alkyl esters of 1-methylcyclopropanecarboxylic acid which comprises the steps of (1) converting &ggr;-butyrolactone to &agr;-methyl-&ggr;-butyrolactone; (2) converting the &agr;-methyl-&ggr;-butyrolactone from step (1) to an alkyl 4-halo-2-methylbutyrate; (3) producing a xylene solution of the alkyl 4-halo-2-methylbutyrate; and (4) contacting the xylene solution of an alkyl 4-halo-2-methylbutyrate from step (3) with an alkali metal alkoxide under conditions of temperature and pressure which causes vaporization of (i) an alkanol as it is formed and (ii) an alkyl 1-methylcyclopropanecarboxylate as it is formed from the alkyl 4-halo-2-methylbutyrate. Also disclosed are processes whereby the alkyl 1-methylcyclopropanecarboxylate, prepared as described above, is converted to 1-methylcyclopropylamine.

This invention relates to an aqueous coating composition comprising a stable dispersion of resin particles and a coalescing agent wherein the coalescing agent is an alkyl 3-alkoxypropionate having the structure:

Use of alkyl 3-alkoxypropionates as coalescing agents in aqueous coating

Disclosed is a process for making quinones by oxidation of dihydroxyaromatic compounds in the presence of oxygen using supported platinum catalysts.

Oxidation of dihydroxyaromatic compounds to quinones

Method for the highly selective transesterification of alkyl 3-alkoxypropionates, as well as several novel alkoxypropionate compounds, are provided. Transesterification catalyzed by titanium alkoxides or tin compounds does not catalyze the Michael reaction, and therefore, provide highly selective transesterification reactions of these reactive materials.

Transesterification of alkoxyesters

Disclosed is an improved process for the preparation of alkyl 3-alkoxypropionates by the reaction of a dialkoxymethane with a diketene in the presence of methanedisulfonic acid, methanetrisulfonic acid or mixture thereof.
