Abstract: This invention relates to a process for preparing amido-carboxylic acids in water. The process involves four steps. Step (A) involves hydrolyzing a lactam at a temperature of 150 DEG C - 300 DEG C to form a mixture containing an amino acid. Step (B) involves cooling the reaction mixture formed in step (A) to a temperature of 25 DEG C - 100 DEG C. Step (C) involves reacting a carboxylic acid anhydride with the amino acid formed in step (A) to form a reaction mixture containing an organic layer which contains an amido-carboxylic acid and an aqueous layer. Step (D) involves separating the amido-carboxylic acid containing organic layer from the aqueous layer. The presence of water aids in product isolation by phase separation and recycle of the reactants. Amido-carboxylic acids are used to make bleach activators for detergents.

Abstract: The present invention relates to a process for preparing copolyesters which involves two steps. The first step is a diol interchange step, and the second step is a polycondensation step. More specifically, the process involves (I) reacting in the presence of a polycondensation catalyst a dihydroxy terephthalate-containing compound having formula (1) wherein n is 1 to 10 and at least 99 % of the end groups are ethylene glycol moieties; and 0.01 to 10 moles, based on moles of the dihydroxy terephthalate-containing compound, of a diol, and (II) polycondensing the reaction product of Step (I) to form a copolyester while excess diol is removed until desired molecular weight is obtained. This process does not include a transesterification of a dialkyl ester reaction or an esterification reaction which are usually used to produce copolyesters. Moreover, this process allows for polyethylene terephthalate and copolyesters prepared therefrom to be produced on an integrated production line.

Abstract: Disclosed is a novel process for the manufacture of 2,2,4,4-tetramethylcyclobutane-1,3-diol commencing with the pyrolysis of isobutyric anhydride to produce dimethylketene. Dimethylketene is absorbed into 2,2,4,4-tetramethylcyclobutane-1,3-dione which function as the process solvents for subsequent dimerization of the dimethylketene to 2,2,4,4-tetramethylcyclobutane-1,3-dione followed by the catalytic hydrogenation of the dione to the diol product.
