    Abstract: A polyesterification method comprises steps of mixing, by combining N,N-dialkylformamide dialkyl acetal with a tin catalyst, so as to transfer an alkoxy group from the N,N-dialkylformamide dialkyl acetal to the tin catalyst to obtain a Sn coordination complex; and polymerization, by conducting a ring-opening polymerization of a ester under the catalysis of the Sn coordination complex, and finally to obtain a polyester compound; wherein, the chemical formula of the N,N-dialkylformamide dialkyl acetal is (RO)2CHNR2, with the R being an alkyl group.

  • Publication number: 20120289636
    Abstract: A method for preparation of secondary alcohols with a high proportion of hydroxyl group at the C2 position is disclosed. Alkyl carboxylates, high in alpha-methylcarboxylate content, are produced via reaction of an alpha-olefin and a carboxylic acid in the presence of a cerium catalyst. The resultant alkyl carboxylate is hydrolyzed to yield a secondary alcohol with a high 2-hydroxyl content. The secondary alcohol may be used to prepare esters, especially phthalate esters or cyclohexanoate diesters, which are useful as plasticizers. These esters are more effective as plasticizers than esters derived from other secondary alcohols due to their high C2 point of attachment.

  • Publication number: 20120271030
    Abstract: A catalyst composition comprises the reaction product of an alkoxide or condensed alkoxide of a metal M, selected from titanium, zirconium, hafnium, aluminium, or a lanthanide, an alcohol containing at least two hydroxyl groups, a 2-hydroxy carboxylic acid and a base, wherein the molar ratio of base to 2-hydroxy carboxylic acid is in the range 0.01-0.79:1. The composition is useful as a catalyst for esterification reactions, especially for the production of polyesters such as polyethylene terephthalate, polytrimethylene terephthalate and polybutylene terephthalate.
