DEET (chiRungu diethylmethylbenzamide), ine zita rekemikari inonzi diethyltoluamide, inodzinga zvipembenene zvakasiyana-siyana. Chemicalbook ine mhedzisiro inodzinga pamhando dzakasiyana dzezvipembenene zvinoruma munzvimbo dzakasiyana siyana uye inogona kudzinga nhunzi dzinoruma. , makudo, nhunzi nhema, chiggers, mhembwe, nhata, unyunyu, nhunzi dzemabhiza, umhutu, nhunzi dzejecha, unyunyu, nhunzi dzakagadzikana nezvikwekwe.

makemikari zvinhu

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 iri 0.996 kusvika 0.998, uye viscosity pa30 ° C ndeye 13.3 centimita Chemicalbook poise. Iyo acute oral LD50 kukosha kwerume chena rats ndeye 2000mg/kg; kudyisa makonzo nechikafu chine 1% DEET kwemazuva 200 hakuna migumisiro yakaipa; iyo uniluted compound inogona kutsamwisa mucous membranes, asi shandisa repellent concentration yeDEET pachiso chako nechiso mazuva ese Pamaoko, inongokonzera 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.
