硫酸二甲酯是胺和酚的有效甲基化剂,广泛用于有机合成工业,并用作矿物油的分离。由于它是一种含有稀硫酸的有机溶剂性的化合物,因而具有较强的侵蚀性能,厚度为6毫米的碳钢管,用作生产装置中的工艺管道,使用寿命仅半年左右,由于腐蚀产物的生成,产品中将含大量铁离子,严重影响硫酸二甲酯的产品质量。为了解决腐蚀和铁离子对产品的污染,上海
Dimethyl sulfate is a useful methylating agent for amines and phenols and is widely used in the organic synthesis industry and for the separation of mineral oils. Because it is a dilute sulfuric acid containing organic solvent compounds, and therefore has strong corrosion resistance, the thickness of 6 mm carbon steel pipe, used as a production process pipeline equipment, the service life of only about six months, the corrosion products Generated, the product will contain large amounts of iron ions, seriously affecting the quality of dimethyl sulfate products. In order to solve the corrosion and iron ion pollution of products, Shanghai
