Ko te DEET (Ingarihi diethylmethylbenzamide), ko tōna ingoa matū ko diethyltoluamide, he rongoā ārai pepeke whānui. He pānga ārai pepeke a Chemicalbook ki ngā momo pepeke ngau i roto i ngā taiao rerekē, ā, ka taea te ārai i ngā namu wero. , ngā namu pīrere, ngā namu pango, ngā namu tītī, ngā namu tia, ngā puruhi, ngā namu hoiho, ngā waeroa, ngā namu onepu, ngā namu, ngā namu tū me ngā tikā.

ngā āhuatanga matū

He wai kore tae, he wai karaka rānei. He kakara citrus māmā. Kāore e memeha i roto i te wai, engari ka taea te whakaranu ki te etanoru, te 2-propanol, te propylene glycol me te hinu purapura miro. Ko te ihirangi meta-isomer o ngā hua ahumahi he 85 ki te 95%, ko te d24 he 0.996 ki te 0.998, ā, ko te matotoru i te 30°C he 13.3 henimita te poise Chemicalbook. Ko te uara LD50 waha koi o ngā kiore mā tāne he tata ki te 2000mg/kg; ko te whāngai ki ngā kiore me te kai kei roto he 1% DEET mō ngā rā 200 kāore he pānga kino; ka taea e te matū kāore i whakananua te whakapataritari i ngā kiriuhi mucous, engari whakamahia te kukū DEET ārai ki tō mata me tō kanohi i ia rā. I ngā ringa, ka puta he whakapataritari ngawari noa iho.

Kaupapa:

Hei ārai pepeke, ko te DEET te matū matua mō te ārai i ngā namu totoka me te wai. He pānga motuhake tōna ki te ārai i ngā namu. He pānga ārai ngā isomer e toru ki ngā namu, ā, ko te meta-isomer te mea tino kaha. Te Whakarite: 70%, 95% wai.
