Technology Overview
Phthalate-Free Safe & Eco-Friendly Plasticizer Technology
Plasticizer is a vital industrial raw material in our daily necessities, and the most widely used type today is Phthalate Esters, a group of environmental hormones that has been phased out in many countries. Given that the use of phthalate-free safe and eco-friendly plasticizer has become a trend for the petrochemical industry, ITRI has developed a hydrogenation process using a patented highly active and selective catalyst, and multi-hydrogenation with packed-bed reactors in series. The new process can directly hydrogenate Phthalate Esters (e.g. DOP/DINP) into a phthalate-free, safe and eco-friendly plasticizer under relatively low pressure, temperature and hydrogen-oil ratio, thereby reducing the process cost and safety risk.
Applications & Benefits
This multi-step connected reaction manufacturing process uses a low-cost single-tube fixed-bed reactor instead of costly multi-tube units to reduce facility construction and operating costs. This technology has been transferred to Taiwan’s manufacturers.
