Product Description

Introduction

Product Name: Triphenyl Thiophosphate CAS Number: 597-82-0
Molecular Formula: C 18 H 15 O 3 PS Molecular Weight: 342

It is obtained by reacting with phenol and phosphorus trichloride through sulfurization, neu- tralization, washing and crystallization. It is widely used in lubricant, esters, etc. Adding a small amount of this additive can improve its extreme pressure, anti-wear, anti-oxidation, hydrolysis safety, and anti-emulsification.
