ʻO 2-(4-methylthiazol-5-yl)ethyl butyrate, ka mea hoʻoheheʻe kemika C11H15NO2S, he pūhui mea ola. He wai waihoʻoluʻu ʻole a ʻeleʻele paha me kahi ʻala kūikawā.

 

Hoʻohana mau ʻia kēia pūhui ma ke ʻano he meaʻai a me nā mea hoʻohui ʻono, loaʻa nā mea ʻala ʻono, a hoʻohana mau ʻia i nā meaʻai a me nā huahana mālama pilikino e like me nā mea ʻono, essences a me nā ʻala e hoʻonui ai i ko lākou ʻono a ʻala paha.

 

Hoʻohui ʻia ia e ka esterification. ʻO ka mua, hoʻopili ʻia ka 2-mercaptoethanol me 4-methyl-5-thiazolylaldehyde e hana i ka 4-methyl-5-thiazolylethanol. Hoʻopili ʻia ka hopena 4-methyl-5-thiazolylethanol me ka butyric anhydride e hana i ka huahana hope 2-(4-methylthiazol-5-yl)ethyl butyrate.

 

Ke hoʻohana nei i kēia pūhui, pono ʻoe e hoʻolohe i kona palekana. He hopena hoʻonāukiuki paha ia ma ka maka a me ka ʻili, a no ka poʻe hapa manawa a me ka poʻe paʻakikī, hiki ke hoʻoulu i nā hopena maʻi. No laila, i ka hoʻohana ʻana a i ʻole ka hana ʻana, pono e ʻaʻahu i nā mea pale kūpono, e like me ka hoʻohana ʻana i nā mīkina lima, nā goggles, etc.

 

Eia kekahi, pono e pale aku i ka launa pū ʻana me nā oxidants a me nā kumu ahi i ka wā e mālama ai i kēia pūhui, a e mālama i kahi ʻano maikaʻi. I ka leakage a ulia paha, pono e lawe koke ʻia nā ʻano hoʻomaʻemaʻe kūpono e pale aku i nā hopena ʻino i ke kaiapuni a me ke kino kanaka.

 

ʻO ka ʻōlelo maʻamau, ʻo 2-(4-methylthiazol-5-yl)ethyl butyrate kahi meaʻai maʻamau a me nā mea ʻala, akā pono e hoʻolohe i ka palekana a lawe i nā hana pale kūpono i ka wā e hoʻohana ai.
