2, β - chloric propane of methylic annulus oxygen
β - chloric propane of methylic annulus oxygen (β - Methyl Fpichlorohydrin) the C that is the generation in using oil hot tearing to solve4 Cent of heat up in a steamer, namely butane - butene heat up in a steamer is divided (abbreviation is divided for B-B heat up in a steamer) medium different butene constituent, a series of reaction make under the course:
β - the structure of chloric propane of methylic annulus oxygen is as follows.
Chloric propane of its basic and chemical function and annulus oxygen is identical, but because be in β on many one methylic, annulus oxygen base active had apparent fall. By it accordingly the career of epoxy resin solidify that makes is slowed, calorific amount is small when solidify, have longer service life.
3, double phenolic A and its ramification
Double phenolic A (Bisphenol A) among them alphabetical A indicates one of producer goods is acetone. (Acetone) by Geneva nomenclature it should be called 2, 2 ′ - double - (4- hydroxide phenyl) - propane or call 2 phenol base propane, 4, 4 ′ - 2 hydroxyl 2 phenyl propane. Structural style is as follows:
Empirical formula C15H16O2, the element is measured 228.29
(one) physical property
The physical property of double phenolic A sees watch 5-5.
Double phenolic A can be mixed mellow, ammonia, amine forms third of phenol, different to be the crystallization that waits for Maerbi to add normally close matter. These adding close matter very flabby calm, it is bath still is in no matter often press, heat below vacuum or inert gase circumstance, all can cause decompose.
(2) chemistry
Because double phenolic A has benzene annulus and hydroxyl presence inside chemistry structure, reason shows weak acidity. Molecular memory is in by ester a group of things with common features catenary is connected two the hydroxide phenyl that rise is round, among them base the substituent that the group is like to be another appropriative electron to accept put oneself in another's position base, its acidity is accordingly some stronger than phenol. Its electron passes 2 hydroxyl of double phenolic A benzene annulus to adipose the direction of season carbon atom of a group of things with common features catenary is mobile, make hydroxide benzene and this between carbolic atom catenary that connect to it become loose, accordingly double phenolic A is when high temperature or be in acerbity, alkaline, heavy nitrogen, inferior in nitric acid medium incidental decompose.
