|Section2= |Section3= }} 1,2-Cyclohexane dicarboxylic acid diisononyl ester is a plasticizer for the manufacture of flexible plastic articles in sensitive application areas such as toys, medical devices and food packaging. From a chemical point of view it belongs to the group of aliphatic esters. In 2002 BASF started selling 1,2-cyclohexane dicarboxylic acid diisononyl ester under the tradename of ''Hexamoll DINCH'' as an alternative for phthalate plasticizers.〔(Flexible vinyls get new non-phthalate plasticizer. (Keeping Up With Additives). ) (September 1, 2002). ''Plastics Technology''. Allbusiness.com. Accessed 2009-02-12.〕 According to BASF, Hexamoll DINCH is the "most widely used phthalate substitute in the world".〔Sarah Varney (February 12, 2009). (New Safety Law Doesn't Mean All's Well In Toyland ). NPR. Accessed 2009-02-12.〕 == Production == The two commercial routes to manufacture 1,2-cyclohexane dicarboxylic acid diisononyl ester are the catalytic hydrogenation of diisononyl phthalate〔(Innovative plasticizer alternative to phthalates for non-PVC applications )〕〔Patent WO 99/32427, "Verfahren zur Hydrierung von Benzolpolycarbonsäuren oder Derivaten davon unter Verwendung eines Makroporen aufweisenden Katalysators", July 1, 1999, BASF AG〕 and the Diels-Alder reaction of a maleic acid ester with 1,3-butadiene followed by hydrogenation. In the case of the catalytic hydrogenation the aromatic part of the diisononyl phthalate is transformed to a cyclohexane ring by a formal addition of 6 hydrogen atoms while the alkyl and ester groups are not affected by the hydrogenation. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「1,2-Cyclohexane dicarboxylic acid diisononyl ester」の詳細全文を読む スポンサード リンク
