The World's First

Wash-Free DOTP and DOP Technology

No Washing. No Wastewater. No Product Loss.

Lower CAPEX. Lower OPEX. Higher Yield.
 

Developed by the company that introduced patented DOTP technology in 2012
and supplied turnkey plants across four continents.

Why wash-free DOTP production

• Thousands of tons less wastewater
• Lower thermal energy demand
• Reduced product losses
• Smaller equipment footprint
• Lower CAPEX
• Lower OPEX

We Simplified DOTP Production in 2012

CEY Kimya introduced its patented DOTP technology and helped transform DOTP production into a simpler, more accessible, and more economical process in 2012.

Over the years, we successfully delivered turnkey plants and licensed our technology to plasticizer manufacturers across four continents, including companies with decades of experience in DOP and DOTP production.

Today, after more than a decade of industrial experience, we are introducing the next generation of DOTP technology.

Wash-Free DOTP Technology in 2025

Conventional DOTP processes require cooling, caustic water washing, phase separation, reheating, and drying. CEY Kimya's Wash-Free Technology eliminates all stages of washing.

Neutralization is completed under vacuum at process temperature, excess 2-EH is removed under vacuum, odor is eliminated by stripping, and the product is sent directly to filtration.
