Hoʻolauna

ʻO 4-Methyl-5-vinylthiazole kahi mea hoʻohuihui,

 

ʻO nā waiwai kino o 4-methyl-5-vinylthiazole ka wai kala ʻole me kahi ʻala like ʻole. Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me ka ethanol a me ka etera a hiki ʻole ke hoʻoheheʻe ʻia i ka wai.

Hoʻohana ʻia ia i ka hana ʻana i nā catalysts a me nā mea polymer.

 

ʻO ka hoʻomākaukauʻana i ka 4-methyl-5-vinylthiazole e pili ana i ka vinyl thiazole, a laila e hoʻopiliʻia me ka methyl sulfide e loaʻa ai ka huahana i manaʻoʻia. Hiki ke kohoʻia keʻano hoʻomākaukau kūikawā e like me nā pono a me ka maʻemaʻe i makemakeʻia.

Hiki ke hoʻonāukiuki a hoʻomāinoino i nā maka a me ka ʻili, a pono e hoʻohana ʻia nā aniani pale a me nā mīkina lima i ka wā o ka hana. Hiki ke ahi a pono e pale ʻia mai nā wela kiʻekiʻe a me nā kumu hoʻā.
