2-3-Diethyl-5-Methylpyrazine(CAS#18138-04-0 )

Hoʻolauna

ʻO 2,3-Diethyl-5-methylpyrazine he mea hoʻohuihui kino, i kapa ʻia ʻo DEET (N, N-diethyl-3-methylphenylethylamine).

Eia kekahi mau waiwai o 2,3-diethyl-5-methylpyrazine:

1. Nānā: He wai kala ʻole ʻo DEET i ka wai melemele māmā.

2. Aʻala: He ʻala ʻala, ʻala.

3. Solubility: Hiki ke ho'ohehe'e 'ia ka DEET i loko o ka wai'ona, nā etera a me ka nui o nā mea ho'ohenehene, akā he ha'aha'a ka solubility i ka wai.

ʻO ka hoʻohana nui ʻana i ka 2,3-diethyl-5-methylpyrazine ma ke ʻano he repellent no nā maʻi maʻi a me nā maʻi maʻi. He kūpono ia e kūʻē i ka nahu ʻana o nā pepeke like ʻole e like me nā makika, ʻoki, a me nā nalo, a me nā mea ʻē aʻe.

ʻO ke ʻano o ka hoʻomākaukau ʻana i ka 2,3-diethyl-5-methylpyrazine e hana mau ʻia e ka catalytic add reaction o benzylamine a me chloroacetic acid, i mua o ka alkali, e hoʻoulu i ka N-benzyl-N-methylacetamide, a laila ma o ka dehydration reaction e loaʻa ai. DEET. Hiki ke hoʻololi ʻia ke kaʻina hana hoʻomākaukau kūikawā e like me nā kūlana kikoʻī a me nā reagents reaction.

ʻIke palekana: 2,3-Diethyl-5-methylpyrazine i manaʻo ʻia he palekana ma lalo o nā kūlana maʻamau o ka hoʻohana. Pono e akahele i ka wā e hoʻohana ai i kekahi mau heluna kanaka, e like me nā kamaliʻi, nā wahine hāpai a me ka lactating, a me nā poʻe me ka maʻi ʻaleʻa i ka DEET. ʻO ka hoʻonui lōʻihi ʻana i ka DEET hiki ke hoʻoulu i nā hopena ʻino e like me ka ʻili a me ka ʻeha o ka maka, no laila e holoi pono i kou mau lima a me nā wahi ʻili i ʻike ʻia ma hope o ka hoʻohana ʻana. Inā loaʻa kekahi pilikia a i ʻole nā ​​hopena ʻino, e hoʻopau koke i ka hoʻohana ʻana a nīnau i ke kauka.
