二氯甲烷的用途非常廣泛，因為二氯甲烷的溶解力強和毒性低的特點，它被廣泛的應(yīng)用于電影膠片，涂料的溶解劑，和氣煙霧噴射劑等領(lǐng)域，那么你知道二氯甲烷的穩(wěn)定性如何嗎？下面我們帶著這一系列的問題跟著小編一起來了解一下。
Dichloromethane has a wide range of uses. Because of its strong solubility and low toxicity, dichloromethane is widely used in the fields of film, coating dissolving agent, and aerosol spray agent. Do you know the stability of dichloromethane? Let's take this series of questions and follow Xiaobian to understand it.
1.毒性很小，且中毒后蘇醒較快，故可用作麻醉劑。對皮膚及黏膜有刺激性。年輕成年大鼠經(jīng)口LD50:1.6mL/kg。空氣中高容許濃度500×10。操作時應(yīng)戴防毒面具，發(fā)現(xiàn)中毒后立即脫離現(xiàn)場，對癥。在甲烷的氯化物中小。蒸氣的麻醉性強，大量吸入會引起急性中毒，出現(xiàn)鼻腔疼痛、頭痛、嘔吐等癥狀。慢性中毒時會引起眼花、疲倦、食欲不振、造血功能受損、紅血球減少。液體二氯甲烷與皮膚接觸引起皮炎。大鼠吸入濃度90.5g/m蒸氣90分鐘死亡。嗅覺閾濃度522mg/m，工作場所高容許濃度為1740mg/m。
1. The toxicity is very small, and the recovery is fast after poisoning, so it can be used as an anesthetic. It is irritating to skin and mucous membrane. Oral LD50 of young adult rats: 1.6ml/kg. The high allowable concentration in air is 500 × 10. Gas mask should be worn during operation. If poisoning is found, leave the scene immediately for symptomatic treatment. In the chloride of methane. The steam is strong in anaesthesia, a large amount of inhalation will cause acute poisoning, nasal pain, headache, vomiting and other symptoms. Chronic poisoning can cause blindness, fatigue, loss of appetite, impaired hematopoietic function, red blood cell reduction. Contact of liquid dichloromethane with skin causes dermatitis. Rats died after inhaling 90.5 g / M steam for 90 minutes. The olfactory threshold concentration was 522 mg / M and the high allowable concentration in workplace was 1740 mg / m.
2.穩(wěn)定性:穩(wěn)定。
2. Stability: stable.
3.避免接觸的條件:光照、潮濕空氣。
3. Conditions to avoid contact: light, moist air.
4.聚合危害:不聚合。
4. Polymerization hazard: no polymerization.
5.分解產(chǎn)物:氯化氫、光氣。
5. Decomposition products: hydrogen chloride, phosgene.
