Triethyl phosphate, Cas# 78-40-0, TEP
Triethyl phosphate tep is a high boiling solvent, plasticizer of rubber and plastics, and also a catalyst. The use of triethyl phosphate tep is also used as raw material for preparing pesticide and insecticide. It is also used as an ethylating reagent for the production of vinyl ketone. The following is a detailed description of the use of triethyl phosphate tep:
1. For catalyst: xylene isomer catalyst; Olefin polymerization catalyst; Catalyst for manufacturing tetraethyl lead; Catalyst for manufacturing carbodiimide; Catalyst for replacement reaction of trialkyl boron with olefins; Catalyst for dehydration of acetic acid at high temperature to produce ketene; Catalyst for polymerization of styrene with conjugated dienes; If used in the polymerization of terephthalic acid and ethylene glycol, it can prevent discoloration of fibers.
2. Solvent for: cellulose nitrate and cellulose acetate; Solvent used to maintain the life of organic peroxide catalyst; Solvent for dispersion of ethylene fluoride; Used as peroxide and diluent of curing catalyst for polyester resin and epoxy resin.
3. For stabilizers: chlorine insecticides and stabilizers; Stabilizer of phenolic resin; Solid agent of sugar alcohol resin.
4. For synthetic resin: curing agent of xylenol formaldehyde resin; The softener of phenolic resin used in shell molding; Softener of vinyl chloride; Plasticizer of vinyl acetate polymer; Flame retardant of polyester resin.
