ʻO 4-Methyl-4-(methylthio)pentane-2-one, ʻike ʻia hoʻi ʻo MPTK, he pūhui kūlohelohe. Eia ka wehewehe kikoʻī i ke ʻano, hoʻohana, hana hana a me ka ʻike palekana o MPTK:
ʻAno maikaʻi:
- Ke ʻano: ʻike ʻia ʻo MPTK ma ke ʻano he kala melemele ʻole a māmā paha.
- Solubility: Hiki ke hoʻoheheʻe ʻia ka MPTK i kekahi mau mea hoʻoheheʻe kūlohelohe, e like me ka ether a me ka chloroform, akā hiki ʻole ke hoʻoheheʻe ʻia i ka wai.
E hoʻohana:
- Hoʻohui kemika: Hiki ke hoʻohana ʻia ka MPTK ma ke ʻano he waena i ka synthesis organik no ka synthesis o nā mea hoʻohui organik ʻē aʻe.
- Insecticides: Hiki ke hoʻohana ʻia ka MPTK i mea maka no nā pesticides i ka mahiʻai.
Hanana:
- Loaʻa pinepine ʻia ka MPTK ma ka hopena o nā sulfides me nā alkyl halides. Loaʻa ka thioalkane pili ma ka hana ʻana i kahi alkyl halide me kahi metala sulfide (e laʻa, ka sodium methyl mercaptan). A laila, ma ka hana ʻana i ka thioalkane me ka acetic anhydride a me ka waikawa chloride, ua hana ʻia ka huahana MPTK hope loa.
ʻIke palekana:
- Pono e mālama ʻia ka MPTK mai nā wela kiʻekiʻe a me nā lapalapa ākea, a mālama ʻia ma kahi maloʻo maloʻo i hoʻopaʻa ʻia a hoʻopaʻa ʻia.
- E hoʻohana i nā lako pale pilikino kūpono, me nā aniani pale kemika a me nā mīkina lima, i ka wā e hoʻohana ai i ka MPTK e pale i ka hoʻopili pololei ʻana me ka ʻili a me nā maka.
- Pono e mālama ʻia e pale i ka hanu ʻana i ka lepo a i ʻole ka mahu i ka wā e lawelawe ai i ka MPTK, a pono e hoʻohana i nā mea hanu inā pono.
- Inā ʻoe e ʻai a hui pū me MPTK, e ʻimi i ka lāʻau lapaʻau a lawe pū me ʻoe i ka ʻeke a i ʻole ka lepili i hiki i kāu kauka ke ʻike i nā mea ʻai.
