氫氧化鉀廠家為您講解:
Dichloromethane is an organic compound with the chemical formula CH_ 2Cl_ 2. It is a colorless and transparent liquid at room temperature and pressure, toxic and flammable. What are its characteristics and reactions? The following potassium hydroxide manufacturer will explain to you:
溶解性強:二氯甲烷在常溫下易溶于大部分有機溶劑,如乙醇、乙醚、苯等,不易溶于水。
Strong solubility: Dichloromethane is easily soluble in most organic solvents such as ethanol, ether, benzene, etc. at room temperature, but not in water.
穩(wěn)定性差:二氯甲烷對熱和光的穩(wěn)定性較差,易被氧化降解,生成有毒的氯化氫。
Poor stability: Dichloromethane has poor stability to heat and light, is prone to oxidative degradation, and generates toxic hydrogen chloride.
揮發(fā)性強:二氯甲烷具有較高的揮發(fā)性,可在常溫下快速揮發(fā)成為有毒氣體。
Strong volatility: Dichloromethane has high volatility and can quickly evaporate into toxic gases at room temperature.
反應活性高:二氯甲烷具有較高的反應活性,在一定條件下可與氫氣、氫化鈉等發(fā)生反應,生成不同的產(chǎn)物。
High reaction activity: Dichloromethane has high reaction activity and can react with hydrogen, sodium hydride, etc. under certain conditions to generate different products.
毒性:二氯甲烷具有較強的毒性,吸入過量會影響神經(jīng)系統(tǒng)和肝臟,對皮膚和眼睛也有刺激作用。
Toxicity: Dichloromethane has strong toxicity, and excessive inhalation can affect the central nervous system and liver, as well as have irritating effects on the skin and eyes.
二氯甲烷主要用于油漆溶劑、去涂劑、脫脂劑、油脂提取劑、泡沫塑料發(fā)泡劑等領(lǐng)域。在制藥業(yè)中,二氯甲烷可以作為藥物的溶劑,以及作為一些藥物的制備中間體。在電子業(yè)中,二氯甲烷是制造多層印刷電路板的溶劑之一。除此之外,二氯甲烷還可以用作燃料和氣體的抑制劑,防止其爆炸。
Dichloromethane is mainly used in paint solvent, paint remover, degreaser, grease extractor, foam plastic foaming agent and other fields. In the pharmaceutical industry, dichloromethane can be used as a solvent for drugs and as an intermediate for the preparation of some drugs. In the electronics industry, dichloromethane is one of the solvents used to manufacture multi-layer printed circuit boards. In addition, dichloromethane can also be used as a fuel and gas inhibitor to prevent its explosion.
值得注意的是,二氯甲烷是一種有毒物質(zhì),長期使用或大量吸入容易引起頭痛、昏迷、甚死亡,應在通風良好的環(huán)境下使用,并嚴格遵守防護措施。
It is worth noting that dichloromethane is a toxic substance that can cause headaches, coma, or even death if used for a long time or inhaled in large amounts. It should be used in a well ventilated environment and safety precautions should be strictly followed.
In short, dichloromethane has high reactivity and toxicity, and should be properly treated and strictly controlled for use. If you have any questions or needs, feel free to contact us at any time http://www.laiyanglicheng.com Come on!
