| Introduction | oxalyl chloride is a kind of synthetic intermediate of medicine, pesticide, in medicine used as raw materials for the synthesis of antibiotics, in the coating used as raw materials for methacryloylphthalein isocyanate, pesticide industry for the synthesis of ultra-efficient sulfonylurea herbicides benzyl Huanglong, plant growth regulators, etc, it is widely used. |
| Use | oxalyl chloride, also known as oxalyl chloride, is an intermediate of benzoylurea insecticides, such as fluifolide, it is also an intermediate of sulfonylurea herbicides such as metsulfuron-methyl, bensulfuron-methyl, pemisulfuron-methyl and the like. In addition, it can also be used in medicine as a raw material for the synthesis of antibiotics. used in the synthesis of organic chlorides. Used as a military gas. commonly used as a military use of toxic gases, but also as a chlorinating agent in organic synthesis for the preparation of organic chlorides mainly used for sulfonylurea herbicides, pesticides, an important raw material for the synthesis of pharmaceutical chemistry intermediates, but also polyamide, Chemical Luminescence agent, high quality acylating agents in chemical industry such as liquid crystals are mainly used for the synthesis of pesticides and pesticide intermediates and for the synthesis of other organic chloride analysis reagents. It is mainly used as an important raw material intermediate for the synthesis of sulfonylurea herbicides, pesticides and medicinal chemistry. It is also a high quality acylating agent in the chemical industry such as polyamide, Chemical Luminescence agent, liquid crystal and other fields. |
| production method | prepared by the reaction of anhydrous oxalic acid and phosphorus pentachloride. The preparation method is to obtain oxalyl chloride by reacting oxalic acid with phosphorus pentachloride. The reaction equation is shown in the figure. After phosphorus pentachloride and anhydrous oxalic acid are mixed uniformly, they are slowly heated to about 64 ° C. And reacted until almost no hydrogen chloride is released, and the obtained crude product is further subjected to rectification to obtain oxalyl chloride. |
