爆炸物危险特性:与空气混合明火、受热可爆
急性毒性:吸入-大鼠LC50:5300 毫克/立方米/4小时; 口服-大鼠LD50:1800 毫克/公斤
下游产品:三甲基氯硅烷 --> 2-氨基-5-甲基吡啶 --> 甲硫醇,压力包装,约为22克。 --> 二氯二甲基硅烷 --> 甲基纤维素 --> 氟虫腈 --> 姜黄素 --> 1,2,4,5-四甲苯 --> 2,2-双(4-羟基苯基)丙烷聚碳酸酯 --> 甲基三氯硅烷 --> 羟丙基甲基纤维素 --> 邻苯二甲醚 --> 2-正丁基-2-苯基-3-(1H-咪唑-1-基)丙腈 --> 缩节胺 --> 头孢地尼 --> 三氟苯唑 --> 麦草畏 --> 十八烷基三甲基氯化铵 --> 咪唑磺隆 --> 烯草酮 --> 法罗培南钠 --> 聚乙二醇二甲醚 --> 二硫基乙酸异辛酯二甲基锡 --> 氯甲基硅烷 --> 异戊二烯-异丁基的共聚物 --> 2-氯丙烯基异硫氰酸酯 --> 甲基二氯硅烷 --> 丁二酰氯 --> 醋硫葡金 --> 氯化三甲基椰子油铵 --> 2,4-戊二烯醛 --> 4,4-二甲基异噁唑-3-酮
用途一:用于生产甲基氯硅烷、四甲基铅、甲基纤维素等，少量用于生产季铵化合物、农药，在异丁橡胶生产中用作溶剂
毒性分级:中毒
储运特性:库房通风低温干燥; 轻装轻卸; 与氧气、空气等助燃气体钢瓶分开存放
上游原料:盐酸 --> 甲醇 --> 氯 --> 四氯化碳 --> 氯化锌 --> 酸性氧化铝 --> 三氯乙醛 --> O,O-二甲基-(2,2,2-三氯-1-羟基乙基)磷酸酯 --> 磷胺 --> 久效磷
MOL 文件:74-87-3.mol
防护措施:有毒。小鼠LC0.003146。由于氯甲烷具有香气，作用缓慢（迟效性），刺激和麻醉作用都较弱，即使到了危险浓度，中毒者仍感觉不到，因此慢性中毒的情况较多。工作场所空气中最高容许浓度80mg/m3。长时间吸入少量蒸气会发生慢性或亚急性中毒，从眩晕、酒醉样症状进而引起食欲不振、嗜睡、行走不使、行动失灵等，还可能出现视觉障碍。大量吸入会损害心肌，与液体氯甲烷接触，可致冻伤。症状严重时，则呈现痉挛、昏睡而致死。中毒后应立即离开现场，急救治疗。
蒸气压:3796 mm Hg ( 20 °C)
可燃性危险特性:明火、受热可燃; 燃烧产生有毒氯化物烟雾
外观性质:无色气体，有醚样的微甜气味。
Sigma Aldrich:74-87-3(sigmaaldrich)
用途二:有机合成的重要原料。主要用来生产有机硅化合物-甲基氯硅烷，以及甲基纤维素。还广泛用作溶剂、提取剂、推进剂、致冷剂、局部麻醉剂、甲基化试剂，用于生产农药、医药、香料等。全世界生产的氯甲烷中，约80%用来生产甲基氯硅烷和四甲基铅，但由于汽油中的抗爆化合物正逐渐由无铅物代替，因此四甲基铅的消费逐渐下降。
类别:可燃气体
灭火剂:雾状水、泡沫
方法一:氯甲烷的生产方法较多，包括甲烷氯化法、甲醇氯化法、光氯化法、氧氯化法等。一些工业过程也副产氯甲烷，例如敌百虫、三氯乙醛、天然气氯化制四氯化碳及磷胺等的生产过程。1.甲烷热氯化法由甲烷直接氯化而成，然后从生成的各种氯化物中分离而得。此法生产流程与二氯甲烷生产相似。在420℃反应条件下，配比为甲烷：氯气=10-6：1时，主要得到氯甲烷。2.甲醇氯化法由甲醇与氯化氢作用而得。此法又分液相法和气相法。（1）液相法甲醇气体和盐酸在氯化锌水溶液中，于130-140℃下反应生成氯甲烷，再经水洗、冷却、压缩、冷凝而得。（2）气相法在350℃使甲醇和氯化氢气体通过固体氧化铝催化剂反应而成。此外，曹德公司以甲醇和氯为原料，制取氯甲烷，对高温气相法有所改进，已实现工业化。3.甲烷氧氯化法它采用连续循环的熔融无机盐作催化剂，经催化氮
常规方法:经加压液化后在500kg或1000kg钢瓶或槽车中贮运。装料量为300kg或500kg，禁止超装。与空气形成爆炸性混合物，爆炸极限8.1%～17.2%(体积），处理、贮运均应通风良好，避免曝晒，保持在40℃以下。按有毒物品规定贮运。
