It is a transparent liquid with a strong sulfide odor, odor and toxicity. This product is the intermediate of pharmaceutical fenalol and is also used as a stabilizer for polyvinyl chloride. CAS NO.: 107-96-0 EINECS:203-537-0 Molecular formula: C3H6O2S Molecular weight: 106.14 1.Physical and chemical properties of 3-Mercaptopropionic acid Properties: Transparent liquid with strong sulfide odor, odor and poison. Density: 1.22g/cm3 (25℃) Melting point: 16.8℃ Boiling point: 111.5°C (2.0kPa) Refractive index: 1.491-1.493 Flash point: 93℃ Solubility: soluble in water, soluble in most organic solvents such as ethanol, benzene, toluene, ether, chlorinated hydrocarbons 2.Use of 3-Mercaptopropionic acid 3-Mercaptopropionic acid is an intermediate of the pharmaceutical fennel and is also used as a stabilizer for polyvinyl chloride. It can be used in transparent products like thioglycolic acid, and its thermal stability is very good, which is better than other stabilizers. Also used as antioxidants, catalysts and biochemical reagents. 3.Production method of 3-Mercaptopropionic acid It is prepared from acrylonitrile and thiourea as raw materials. First, thiourea and hydrochloric acid were reacted at 40°C for 0.5h, acrylonitrile was added dropwise, reacted at 110-113°C for 3h, cooled to 40°C, and 4% sodium hydroxide solution was added to pH 11, after dehydrogenation for 4h, at 30°C ℃ neutralize with hydrochloric acid to pH 1-2. Then add benzene to extract, recover benzene, carry out vacuum distillation, collect 125-140 ℃ fractions to obtain the finished product. In addition, 3-3-Mercaptopropionic acid can also be obtained by the reaction of hydrogen sulfide with pyruvic acid or with β-propiolactone. 4.3-Mercaptopropionic acid transportation and storage method Store in a cool, ventilated warehouse. Keep away from fire and heat sources. It should be stored separately from oxidants, reducing agents and alkalis, and should not be mixed. Equipped with the appropriate variety and quantity of fire equipment. Storage areas should be equipped with emergency release equipment and suitable containment materials. 更多 供应商信息 江苏科昌化工有限公司 认证状态： 未认证供应商 电话： +86512-58813105 地址： 江苏省张家港市杨舍镇滨河路2号 区域： 江苏省 苏州市 张家港市 联系人： Xiao 联系人电话： 13773214532 邮件： [email protected] 网址： www.clentpharma.com 江苏科昌化工有限公司是一家集研发、生产、营销为一体的高新手艺企业，具有多年医药中央体和保健营养质料产物的生产履历。 我们的主要产物包罗：2,2-联吡啶（cas#366-18-7）和庚炔（2-Amino-5-nitrothiazole, cas#121-66-4）和2-氨基噻唑（cas#96-50-4） ) 主要是氨基酸、草本提取物、维生素、甜味剂、其他功效弥补剂。
