Wei promise glycol solvent mainly used for making polyester polyester, polyester resin, moisture, plasticizers glycol antifreeze, surfactants, synthetic fibers, cosmetics glycol prices, and used as a dye, ink, etc. , formulated engine antifreeze, gas dehydration agent, manufacture of resins, can also be used for cellophane, fiber, leather, adhesives humectant. Qingdao-Connaught ethylene glycol: in the presence of an acid or a base, with an aldehyde or ketone condensation reaction of a ketone alcohol, an unsaturated ketone and resinous substance. With phenol under acidic conditions glycol coolants, condensed bisphenol -A. Α- acetone hydrogen atom is easily substituted with halo, halo generating α- acetone. And the role of alkaline solution of sodium halide or halogen second generation Haloform. An addition of acetone with a Grignard reagent, hydrolysis to give the tertiary alcohol addition products. Acetone with ammonia and derivatives thereof such as hydroxyl ammonia, hydrazine, phenylhydrazine, etc. can also be a condensation reaction. In addition, the occurrence of cracking in acetone 500 ~ 1000 ℃, the generated ketene. [8] at 170 ~ 260 ℃ by silica - alumina catalyst to produce isobutene and acetaldehyde; generate isobutene and acetic acid, etc. at 300 ~ 350 ℃. [9] can not be a silver ammonia solution, freshly prepared copper hydroxide and other weak oxidants, but the catalytic hydrogenation of alcohol.
