新《生活饮用水卫生标准》GB5749- 项目解读:环氧氯丙烷

关键词：标准 GB 生活饮用水饮用水生活饮用水卫生标准

环氧氯丙烷；1-氯-2,3-环氧丙烷,氯甲代氧丙环
Epich lorohydrin；Chloromethyloxiran,1-Chloro-2,3-epoxypropane
分子式： O C H 2 C H C H 2 Cl
简称 ECH

分子量： C3H5ClO=92.58
性　　状：无色或浅黄色透明液体。易挥发。能与醇、醚、三氯甲烷相混溶；不溶于水。
环氧氯丙烷是一种重要的有机化工原料和精细化工产品，用途十分广泛。以它为原料制得的环氧树脂具有粘结性强，耐化学介质腐蚀、收缩率低、化学稳定性好、抗冲击强度高以及介电性能优异等特点，在涂料、胶粘剂、增强材料、浇铸材料和电子层压制品等行业具有广泛的应用。此外，环氧氯丙烷还可用于合成甘油、硝化甘油炸药、玻璃钢、电绝缘品、表面活性剂、医药、农药、涂料、胶料、离子交换树脂、增塑剂、（缩）水甘油衍生物、氯醇橡胶等多种产品，用作纤维素酯、树脂、纤维素醚的溶剂，用于生产化学稳定剂、化工染料和水处理剂等。

Consumption Patterns

Epoxy resins, 65%; glycerine, 25%; epichlorohydrin elastomers, 5%; miscellaneous, 5% (1984)

Apparent Color

COLORLESS, MOBILE LIQ

Odor

ODOR IS GENERALLY PERCEIVED AS A SLIGHTLY IRRITATING CHLOROFORM-LIKE ODOR. ; Pungent, garlic; sweet

Boiling Point

116.5 DEG C

Melting Point

-48.0 DEG C

Molecular Weight

92.53

Density

1.1801 @ 20 DEG C/4 DEG C

Odor Threshold Concentration

SENSORY PERCEPTION STUDIES INDICATE THAT MEAN THRESHOLD FOR ODOR RECOGNITION IS APPROX 10 PPM @ 25 PPM IT IS RECOGNIZED BY MAJORITY OF PERSONS. Human Odor Perception: non perception 0.2 mg/cu m; perception 0.3 mg/cu m

Sensitivity Data

MARKED NOSE & EYE IRRITATION OCCUR ONLY ABOVE 100 PPM. Epichlorohydrin effect on the skin, eyes, and respiratory tract may be delayed for several hours. Epichlorohydrin causes dermatitis. Inhalation of epichlorohydrin causes irritation of the eyes and throat.

Environmental Impact

Epichlorohydrin may be released to the atmosphere and in wastewater during its production and use in epoxy resins, glycerin manufacture, as a chemical intermediate in the manufacture of other chemicals, and other uses. If released into water it will be lost primarily by evaporation (half-life 29 hr in a typical river) and hydrolysis (half-life 8.2 days). It will neither<
