1.避免接觸潮濕空氣。避免與強(qiáng)氧化劑、強(qiáng)還原劑、強(qiáng)酸、強(qiáng)堿、堿金屬、水接觸。斜方晶系無(wú)色針狀或片狀結(jié)晶體。溶于水生成順丁烯二酸。溶于乙醇并生成酯。溶于乙醇、乙醚等多種有機(jī)溶劑,難溶于石油醚和四氯化碳。與熱水作用生成順丁烯二酸酐
1. Avoid contact with humid air. Avoid contact with strong oxidant, strong reducing agent, strong acid, strong alkali, alkali metal and water. Orthorhombic crystal is colorless acicular or flaky crystal. It is soluble in water to form maleic acid. It dissolves in ethanol and forms ester. It is soluble in ethanol, ether and other organic solvents, but insoluble in petroleum ether and carbon tetrachloride. It reacts with hot water to form maleic acid.
易于烯類單體進(jìn)行共聚反應(yīng);也可進(jìn)行均聚。與二元醇反應(yīng)生成線型不飽和聚酯,與三氧化硫反應(yīng)生成磺化順丁烯二酸酐??扇肌S卸?,濺及皮膚時(shí)要用大量清水沖洗。設(shè)備要密閉,操作人員要穿戴好防護(hù)用具。
It is easy to carry out copolymerization of olefin monomers and homopolymerization. Linear unsaturated polyester was formed by reaction with diols, and sulfonated maleic anhydride was formed by reaction with sulfur trioxide. Combustible. Toxic. Wash with plenty of water when splashing on skin. The production equipment should be sealed and the operators should wear protective equipment.
順丁烯二酸酐
2.該品有毒。其毒性比順?biāo)岽螅艽碳てつw及黏膜。當(dāng)人體接觸高溫液體時(shí),其刺激性更為嚴(yán)重,能造成皮膚灼燒傷,結(jié)膜、角膜紅腫,嚴(yán)重時(shí)導(dǎo)致視力減退甚失明。
2. The product is poisonous. It is more toxic than CIS acid and can stimulate skin and mucous membrane. When the human body is exposed to high temperature liquid, its irritation is more serious, which can cause skin burn to injury, conjunctiva, corneal redness and swelling, and even lead to vision loss or blindness.
對(duì)大鼠經(jīng)服LD50為400mg/kg。小鼠經(jīng)口LD5060~465mg/kg。在空氣中高容許濃度0.25*10-6。當(dāng)濺及皮膚時(shí)要用大量清水沖洗。設(shè)備要密閉,操作人員要穿戴好防護(hù)用具。
The LD50 of rats was 400 mg / kg. Ld5060 ~ 465mg / kg by oral administration in mice. The high allowable concentration in air is 0.25 * 10-6. When splashing on the skin, rinse with plenty of water. The production equipment should be sealed and the operators should wear protective equipment.
3.存在于煙氣中。
3. Exist in flue gas.
4.強(qiáng)烈的刺激性,引起燒傷,吸入可引起肺水腫。易被酯化。加熱到150℃以上放出乙酸。溶液加熱到100℃發(fā)生分子斷鏈。
4. Strong irritation, cause burns, inhalation can cause pulmonary edema. It is easy to be esterified. When heated to 150 ℃, acetic acid is released. When the solution is heated to 100 ℃, the molecular chain breaks.
