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

Intangiriro

2,3-Diethyl-5-methylpyrazine ni uruganda kama, ruzwi kandi nka DEET (N, N-diethyl-3-methylphenylethylamine).

Ibikurikira nimwe mubintu biranga 2,3-diethyl-5-methylpyrazine:

1. Kugaragara: DEET ni ibara ritagira ibara ryumuhondo.

2. Impumuro: Ifite impumuro nziza, kama.

3. Gukemura: DEET irashobora gushonga muri alcool, ethers hamwe na solge nyinshi, ariko ifite imbaraga nke mumazi.

Ikoreshwa nyamukuru rya 2,3-diethyl-5-methylpyrazine ni nkumuti wica udukoko nudukoko. Ifite akamaro mukuruma udukoko dutandukanye nkumubu, amatiku, nisazi, nibindi. DEET ikoreshwa mugukora ibicuruzwa nko kurwanya udukoko, udukoko twangiza imibu, imiti yica udukoko hamwe nudukoko twangiza udukoko.

Uburyo bwo gutegura 2,3-diethyl-5-methylpyrazine mubusanzwe bukorwa na catalitiki yongeyeho reaction ya benzylamine na acide chloroacetic, imbere ya alkali, kugirango habeho N-benzyl-N-methylacetamide, hanyuma binyuze muburyo bwo kubura umwuma kugirango ubone DEET. Gahunda yihariye yo kwitegura irashobora guhindurwa ukurikije ibihe byihariye na reagent.

Amakuru yumutekano: 2,3-Diethyl-5-methylpyrazine ifatwa nkumutekano mugihe gikoreshwa muri rusange. Ubwitonzi burasabwa mugihe ukoresheje abantu bamwe, nkabana, abagore batwite n'abonsa, nabantu bafite allergie kuri DEET. Kumara igihe kinini uhura na DEET birashobora gutera ingaruka mbi nka allergie y'uruhu no kurakara amaso, bityo rero koza intoki zawe kandi ugaragaze neza uruhu nyuma yo kuyikoresha. Niba hari ibitagenda neza cyangwa ingaruka mbi zibaho, hagarika gukoresha ako kanya hanyuma ubaze muganga.
