| Use | tert-butyl hydrazine hydrochloride, also known as tert-butyl hydrazine hydrochloride, is an important pesticide intermediate, it can be used in the synthesis of benzohydrazide insecticides hydrazine, dihydrazide insecticides tebufenozide, halofenozide, methoxyfenozide and fenozide, and the miticide pyridaben. used as pharmaceutical, pesticide intermediates organic synthesis, pharmaceutical synthesis intermediates, such as the synthesis of rice mites (Tebufenozide). |
| production method | There are several preparation methods of tert-butyl hydrazine hydrochloride reported in the literature. Reaction of chlorinated ammonia with tert-butyl ammonia. Reaction equation: NH2-Cl H2N-C4H9-t → H2N-NH-C4H9-t · HCl diphenyldiazomethane was reacted with Grignard reagent, and the obtained intermediate was subjected to acid hydrolysis. Reaction equation:(C6H5)2C = N2[t-C4H9MgCl]→(C6H5)2 = N-NH-C4H9-t[HCl]→(C6H5)2C = O H2N-NH-C4H9-t · HCl under the action of acid, by hydrazine hydrate and tert-butyl alcohol direct reaction. Reaction equation: NH2NH2 · HCl (CH3)3COH[HCl]→(CH3)3CNHNH2 · HCl 2H2O production generally adopts the third method, the specific process is: hydrazine hydrate and an appropriate amount of hydrochloric acid were added to the enamel reaction kettle, and the temperature was raised to 80 to 90 ° C., and then tert-butanol was added dropwise. After the dropwise addition is completed, Reflux reaction is carried out at 100~105 ℃ for 3H, and the product is obtained by dehydration, cooling to 80 ℃, crystallization, filtration and drying. |
