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 ¡æ, slowly add epichlorohydrin. Add to complete, at 25 ¡æ stirring 45h, the reaction extracted with ethyl ether, anhydrous potassium carbonate extract add dry filter. Recycling ether filtrate by vacuum distillation, collecting 120-123 ¡æ (1.46kPa) distillate is phenyl ether glycidylpropyltrimethoxy.

Uses: used as intermediates in organic synthesis.
