USE OF COMPOUNDS AS PLASTICIZER FOR PVC
Provided is a 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 mor...

| description | Provided is a 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. |
