| Use | 2,2,3,3, 3-tetramethylcyclopropane carboxylic acid chloride is referred to as tetramethyl chrysanthemum chloride, which is a pyrethroid intermediate of fenpropathrin. |
| production method | its preparation method is to put 2,2,3,3, 3-tetramethylcyclopropane carboxylic acid into a reaction kettle, add thionyl chloride dropwise under heating, react for 4 hours under micro negative pressure, then evacuate with a large vacuum to remove excess thionyl chloride, and the residue is tetramethylchrysanthemum chloride. |
