DEET (Chirungu diethylmethylbenzamide), ine zita remakemikari rinonzi diethyltoluamide, mushonga unodzinga zvipembenene zvakasiyana-siyana. Chemicalbook ine simba rekudzivirira zvipembenene zvakasiyana-siyana zvinoruma munzvimbo dzakasiyana-siyana uye inogona kudzinga nhunzi dzinoruma. , midges, nhunzi nhema, chiggers, deer flies, inda, unyunyu, horse flies, umhutu, sand flies, unyunyu, stable flies and ticks

hunhu hwemakemikari

Mvura isina ruvara kana amber. Ine hwema hwe citrus hwakareruka. Hainyungudike mumvura, asi inogona kusanganiswa ne ethanol, 2-propanol, propylene glycol nemafuta ekotoni. Kuwanda kwe meta-isomer muzvigadzirwa zvemaindasitiri kuri pakati pe 85 ne 95%, d24 iri pakati pe 0.996 ne 0.998, uye viscosity pa 30°C ndeye 13.3 centimeters Chemicalbook poise. Kukosha kwe LD50 yemuromo wemakonzo machena echirume kunosvika 2000mg/kg; kudyisa makonzo ane chikafu chine 1% DEET kwemazuva 200 hakuna migumisiro yakaipa; chinhu chisina kusanganiswa chinogona kutsamwisa mucous membranes, asi kushandisa DEET yakawanda inodzinga kumeso kwako nekumeso zuva nezuva. Pamaoko, inokonzera kutsamwa kudiki chete.

Chinangwa:

Semushonga unodzinga zvipembenene, DEET ndiyo inonyanya kushandiswa mumhando dzakasiyana-siyana dzemushonga unodzinga umhutu hwakasimba uye hwemvura. Ine mhedzisiro yakakosha mukudzivirira umhutu. Ma isomers ese matatu ane simba rekudzivirira umhutu, uye meta-isomer ndiyo yakasimba. Kugadzirira: 70%, 95% yemvura.
