标题 :Catalyzed synthesis of aryl-substituted fatty acids and fatty esters and compositions related thereto
发明人：OUDE ALINK BERNARDUS A
权利人:BAKER HUGHES INC
摘要:A novel method for preparing an aryl-substituted fatty acid or fatty ester is disclosed. According to the method, an olefinic composition selected from among mono-unsaturated fatty acids, mono-unsaturated fatty esters and mixtures thereof is introduced to a reaction zone comprising a liquid aromatic hydrocarbon and a catalytic amount of a clay catalyst to produce a reaction that is allowed to proceed for a time and at a temperature sufficient to produce a reaction product comprising a desired yield of aryl-substituted fatty acid or fatty ester. Preferably, the introduction of the olefinic composition is conducted slowly, such as over a period of one to four, more preferably, two to four, hours. Related methods and compositions, including xylylstearic acid, are also disclosed.

标题:Process for the preparation of fast crystallizing polyester compositions
摘要:A process wherein, in a first step, a highly nucleated polyester is prepared with addition of from 2x10<-><2> mol to 1 mol of alkali metal or alkaline earth metal, an alkali metal compound or an alkaline earth metal compound per kg of the polyester to be prepared, at any desired point of the synthesis and subsequently, in a second step, this highly nucleated polyester is admixed with a non-nucleated polyester of the same or different chemical composition to give a rapidly crystallising polyester. The polyesters according to the invention are distinguished, in particular, by improved colour quality and increased processing stability.

摘要:PCT No. PCT/JP95/00423 Sec. 371 Date Aug. 30, 1996 Sec. 102(e) Date Aug. 30, 1996 PCT Filed Mar. 15, 1995 PCT Pub. No. WO95/25133 PCT Pub. Date Sep. 21, 1995A monomer mixture having a hydroxyl value ranging from 0 to 134 KOH mg/g, obtainable by polymerizing a mixed raw material of an unsaturated compound selected from the group consisting of fatty acids each having one carboxyl group and one double bond in the molecule and having 11 to 22 carbon atoms and lower alkyl esters thereof with an unsaturated compound selected from the group consisting of fatty acids each having one carboxyl group and 2 to 4 double bonds in the molecule and having 11 to 22 carbon atoms and whose iodine value ranges from 30 to 130 g (iodine)/100 g to give dimers and trimers, then converting the carboxyl groups (or the lower alkyl ester group in case of the lower alkyl esters) present in the resulting dimers and trimers into hydroxyl groups through reduction to give a mixture substantially consisting of dimer diols and trimer triols, and then subjecting the mixture having a dimer diol/trimer triol weight ratio ranging from 30/70 to 99/1 to an esterification reaction with an alpha , beta -unsaturated carboxylic acid or a transesterification reaction with a lower alkyl ester of an alpha , beta -unsaturated carboxylic acid. The monomer mixture is useful in the synthesis of polymers such as various kinds of resin materials for optical applications.
