Chemical Properties

Mvura isina ruvara kune amber. Iine hwema hwecitrus hwakareruka. Zvinenge zvisinganyunguriki mumvura, asi zvinosanganiswa ne ethanol, 2-propanol, propylene glycol uye mafuta ekotoni. Iyo meta-isomer yemukati yezvigadzirwa zveindasitiri ndeye 85 kusvika 95%, d24 ndeye 0.996 kusvika 0.998, uye viscosity pa30 ° C ndeye 13.Chemicalbook 3 centipoise. Iyo acute oral LD50 kukosha kwerume chena rats ndeye 2000mg/kg; kudyisa makonzo nechikafu chine 1% DEET kwemazuva 200 hakuna migumisiro yakaipa; iyo indiluted compound inogona kutsamwisa mucous membranes, asi shandisa repellent concentration yeDEET pachiso chako nechiso zuva rega rega Pamaoko, zvinongokonzera kushatirwa.

Chinangwa:

Sezvinodzinga zvipembenene, DEET ndiyo inonyanya kudzinga musanganiswa mune dzakasiyana siyana dzakasimba uye dzemvura dzinodzinga umhutu. Iine zvakakosha pakudzivirira umhutu. Ese ari matatu isomers ane chinodzinga umhutu, uye meta-isomer ndiyo yakasimba. Kugadzirira: 70%, 95% mvura.

Nzira yekugadzira:

Inowanikwa kubva mukuita kwem-toluoyl chloride uye diethylamine. Zvigadzirwa zvemaindasitiri zvine 5% -15% isomers.
