  • 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.

  • Patent number: 8299292
    Abstract: Provided is a method for preparing 60% or more cis-di(C4-C20)alkyl cyclohexane-1,4-dicarboxylate which exhibits superior plasticizing property for PVC resin. Instead of a phthalate- or terephthalate-based aromatic ester derivative, 60% or more cis-dimethyl cyclohexane-1,4-dicarboxylate is used as a starting material. The 60% or more cis-dimethyl cyclohexane-1,4-dicarboxylate is subjected to transesterification with (C4-C20) primary alcohol to prepare 60% or more cis-di(C4-C20)alkyl cyclohexane-1,4-dicarboxylate. Methanol produced as a byproduct during the transesterification is removed and some of the primary alcohol, which is evaporated, is recycled. Thus prepared 60% or more cis-di(C4-C20)alkyl cyclohexane-1,4-dicarboxylate exhibits superior plasticizer characteristics, including good plasticizing efficiency for PVC resin, high absorption rate, good product transparency after gelling, less bleeding toward the surface upon long-term use, and the like.

  • Publication number: 20120259131
    Abstract: Disclosed is an improved process for the production of phthalic anhydride wherein the spent catalyst is removed from the oxidation reactor tubes more effectively by vacuuming from the top and using a vacuum hose having a tip with an increased impact strength and with a maximum hardness. As a result, the new catalyst loading can be made more uniform and the process may be operated with improved stability at higher organics loadings in the reactor feed. Process stability may be further improved by varying the outlet temperature of the phthalic anhydride precondenser over time.

  • Patent number: 8273796
    Abstract: The present invention relates to a novel class of polymeric compounds having specific quaternized amine based upon a dimer acid reacted with a combination of a monohydroxy functional amine and a specific di-hydroxy functional tertiary alkanolamine, to make an ester tertiary amine, which is a subsequent step is converted to a quaternary compound. Dimer acid is a C-36 diacid having a cyclic structure and reacting it with the two type of amine groups allow for the synthesis of a high molecular weight cationic compound which is extremely substantitive to human skin and are well tolerated by human tissue making them suitable for use preparation of barrier products for personal care applications. These materials are dimethylaminopropyl amine free, which is highly desirable in personal care applications.

    Abstract: A radiation-sensitive resin composition includes a first polymer including an acid-labile group, an acid generator to generate an acid upon exposure to radiation, and a second polymer including a fluorine atom and a functional group shown by a general formula (x). The second polymer has a fluorine atom content higher than a fluorine atom content of the first polymer. R1 represents an alkali-labile group. A represents an oxygen atom, —NR?—, —CO—O—# or —SO2—O—##, wherein the oxygen atom represented by A is not an oxygen atom bonded directly to an aromatic ring, a carbonyl group, or a sulfoxyl group, R? represents a hydrogen atom or an alkali-labile group, and “#” and “##” indicates a bonding hand bonded to R1.

  • Publication number: 20120226069
    Abstract: A method for preparing esters of cyclohexane polycarboxylic acids from esters of benzene polycarboxylic acids makes improvement to hydrogenation of esters of benzene polycarboxylic acids by using a reaction tank having a gas-introducing mixer capable of extracting and exhausting air and stirring to hydrogenate an ester of a benzene polycarboxylic acids into an ester of a cyclohexane polycarboxylic acid in the presence of a hydrogenation catalyst; resulted in that the method advantageously minimizes the operational pressure for hydrogenating esters of benzene polycarboxylic acids and significantly lowers the reaction temperature for hydrogenation while effectively improving the yield of esters of cyclohexane polycarboxylic acids made from the esters of the benzene polycarboxylic acids.
