(2,3-epoxypropoxy) benzene
Nature Description: colorless
transparent liquid. Melting point 3.5 ℃, boiling point 242.5 ℃
(100kPa), the relative density of 1.1109 (21.2 / 4 ℃), refractive
index 1.5307 (21 ℃). Soluble in ether, benzene, insoluble in water,
can be volatile with steam.
Scientific name 690 epoxy reactive diluent phenyl ether of propylene
oxide, phenol and epichlorohydrin by the open-loop by the ether, and
then obtained by epoxidation of the ether-type reactive diluent.

Features and Application
690 low viscosity epoxy reactive diluent, 0.007Pa s around with
epoxy resin miscible in any proportion. Compared with the 501, 690
molecules containing benzene ring, which epoxy reactive diluent 690
products, heat-resistant than 501 higher.
690 epoxy reactive diluent with the multi-amine reaction can be
obtained epoxy resin curing agent. Such as m-phenylenediamine with
the reaction of epoxy resin curing agent made of 590.
Amount
General usage of 10-15% for the epoxy resin (weight ratio). 690
because of the epoxy containing groups react with the curing agent,
which used to be a corresponding increase in the amount of curing
agent.
Packaging and storage
20Kg plastic barrel, 180Kg drums loaded. 690 as a result of
flammable, volatile chemicals, it is necessary to avoid sunlight and
away from heat, store in a cool well-ventilated place. To prevent
static electricity and open flame contact.
Production methods: by the phenol, sodium hydroxide at the presence
of epichlorohydrin derived from condensation. To phenol, sodium
hydroxide, mixing of all the dissolved, cooling to 5-6 ℃, slowly add
epichlorohydrin. Add to complete, at 25 ℃ stirring 45h, the reaction
extracted with ethyl ether, anhydrous potassium carbonate extract
add dry filter. Recycling ether filtrate by vacuum distillation,
collecting 120-123 ℃ (1.46kPa) distillate is phenyl ether
glycidylpropyltrimethoxy.
Uses: used as intermediates in organic synthesis.
