The main purpose
Triethyl phosphate is a high boiling point solvent and a plasticizer for rubber and plastics. Also a catalyst. It is also used as a raw material for preparing pesticides and insecticides. and as an ethylation reagent for ketene production. In Japan, 70% of this product is used as catalyst and about 20% is used as solvent.
(1) Catalyst: xylene isomer catalyst; olefin polymerization catalyst; catalyst for manufacturing tetraethyl lead; catalyst for manufacturing carbodiimide; catalyst for replacement reaction of trialkyl boron and olefin; high-temperature dehydration of acetic acid to produce ethylene Catalyst for ketones; catalyst for the polymerization of styrene and conjugated diene compounds; if used in the polymerization of terephthalic acid and ethylene glycol, it can prevent fiber discoloration.
(2) Solvents: solvents for cellulose nitrate and cellulose acetate; solvents used to maintain the life of organic peroxide catalysts; solvents used to disperse fluorinated ethylene; peroxides used as curing catalysts for polyester resins and epoxy resins agents and thinners.
(3) Stabilizers: chlorine-based pesticides and stabilizers; stabilizers for phenolic resins; solid agents for sugar alcohol resins.
(4) Synthetic resins: curing agent for xylenol-formaldehyde resin; softening agent for phenolic resin used in shell molds; softening agent for vinyl chloride; plasticizer for vinyl acetate polymer; flame retardant for polyester resin agent.
(5) Triethyl phosphate (flame retardant TEP) is a high boiling point solvent, a plasticizer for rubber and plastics, and is also used as a raw material for the preparation of pesticides and insecticides, as an ethylation reagent and for the production of ketene. In Japan, 70% of this product is used as catalyst.
