(butoxymethyl)-Oxirane；Butyl epoxy propyl ether
bge；bge；butoxymethyloxirane；butyl 2,3-epoxy propyl ether
Molecular formula: C7H14O2
Molecular Weight: 130.18
Boiling Point: 166 ℃
1. brief introduction:
501 epoxy resin active diluent chemical name for the butyl ether of
propylene oxide and epichlorohydrin by the Department of butanol
etherification open-loop re-oxidation by the closed-loop system of a
glycidyl-type epoxy diluent molecules containing live ether key and
epoxy, epoxy resin dilution effect, curing time involved in curing to
form a homogeneous system, are commonly used epoxy resin reactive
Description: colorless transparent liquid. Relative density 0.915,
boiling point 164 ℃, refractive index 1.420, flash point 59 ℃. Soluble
in acetone; benzene; alcohol, insoluble or hardly soluble in water.
Production methods: by the alcohol and epichlorohydrin as raw materials,
was synthesized by two steps. Specific process is: 32kg to 267kg and
butanol concentration of 96% of concentrated sulfuric acid reactor add,
stirring, heating to 55 ℃, epichlorohydrin dropwise 324kg, temperature
control at about 55-60 ℃ increasingly 4h, and then at 60-65 ℃ insulation
2h. Then, cooling to 45 ℃, slowly add four chloride with n-butanol
mixture (5kg tin tetrachloride in n-butanol soluble 5kg), and then heat
at 60-65 ℃ reaction 4h, reaction after vacuum distillation recovery
unreacted epichlorohydrin and of n-butanol until the temperature reaches
85-95 ℃, under vacuum 93.1kPa epichlorohydrin and alcohol-free until
steamed out. Be Epichlorohydrin-butyl ether. Response to the
above-mentioned materials to cold 30-35 ℃, dropping 30% of the sodium
hydroxide concentration of 432kg, plus about 4h End, and then warming to
35-40 ℃ and heat reaction 3h, and then add pure benzene under stirring
at temperature to release out saline and alkaline, and then washed so
that pH of about 6.5-7. Release washing water, atmospheric warming from
benzene, until the liquid temperature to 140 ℃, then cooled discharge.
Two-step to the total yield of about 95% butanol.
Purposes: the goods can be used for bisphenol A epoxy resin reactive
diluent. Toxicity in small and easy to use. And can improve some
properties after hardening resin, such as impact strength.

be widely used in electronics, electrical, electromechanical,
mechanical industry, to reduce viscosity of epoxy is suitable for
potting, casting, impregnating applications such as technology, can
also be used for adhesives.
