Dotp Turnkey Factory - Dotp Factory Installer - Makfen
Makfen manufacture equipment for full technological process of DOTP production
Dioctyl terephthalate (bis(2-ethylhexyl) benzene-1,4-dicarboxylate or Di(2-ethylhexyl) terephthalate), commonly abbreviated DOTP or DEHT, is an organic compound with the formula C6H4(CO2C8H17)2. It is a non-phthalate plasticizer, being the diester of terephthalic acid and the branched-chain 2-ethylhexanol. This colorless viscous liquid used for softening PVC plastics is known for chemical similarity to general purpose phthalates such as DEHP and DINP, but without any negative regulatory pressure. It possesses very good plasticizing properties and may be used as a direct replacement for DEHP and DINP in many applications.
Makfen provides a method of manufacture is a direct esterification of terephthalic acid with 2-ethylhexanol:
C6H4(CO2H)2 + 2 C8H17OH → C6H4(CO2 C8H17)2 + 2H2O
We have wide experience in building of this equipment from project to start-up, that`s why ready to introduce DOTP Material balance, Drawing and pictures from installed objects.
PTA (166 kg) + 2EH (260 kg) → DOTP (390 kg) + WATER (36 kg)
Makfen provided production and installation turnkey DOTP plants with different requests capacity 10 – 20 -40 Tons/day
