Hoʻolauna

ʻO 2-Formylthiazole kahi mea hoʻohuihui.

Solubility: Hiki ke hoʻoheheʻe ʻia i loko o ka wai a hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik he nui, e like me nā waiʻona, eter a me nā ketones.

Paʻa: ʻAʻole paʻa i ka wela a me ka oxygen a maʻalahi ka decomposes.

Reactivity: 2-Formylthiazole hiki ke hoʻokō i kāna hana kemika ma o ka nucleophilic substitution reaction, a hiki i ka acylation, amidation, etc.

 

Nā mea hoʻohana o 2-Formylthiazole:

 

Pesticide: ʻO 2-Formylthiazole kahi lāʻau lāʻau i hiki ke hoʻohana ʻia no ka hoʻopaʻa ʻana i nā pests ma nā mea kanu a me nā kumulāʻau hua.

 

ʻO ka hoʻomākaukau ʻana i ka 2-formylthiazole maʻamau e hana ʻia e nā ʻano hana penei:

 

Nucleoacylation: Hoʻopili ʻia ka Chloroacetyl chloride me ka thioethanol ma lalo o nā kūlana alkaline e hana i ka 2-formylthiazole.

ʻO ka hopena condensation: hiki ke loaʻa ka 2-formylthiazole ma ka hana ʻana i ka acetylacetamide me ka sodium thiocyanate ma lalo o nā kūlana alkaline.

 

ʻO 1.2-Formylthiazole he mea hoʻonāukiuki a hiki ke hōʻeha i ka ʻili a me ka maka ke hoʻopili ʻia. E hoʻohana i nā lako pale pilikino kūpono e like me nā mīkina lima, nā maka aniani, a me nā mea ʻē aʻe i ka wā e hana ai.

E hōʻalo i ka hoʻohu ʻana a i ʻole ka ʻai ʻana i ka 2-formylthiazole a e ʻimi koke i ka lāʻau lapaʻau inā ale ʻia a hoʻohu ʻia paha i ka nui.

Pono e mālama ʻia ka 2-Formylthiazole ma kahi ʻoluʻolu a maikaʻi hoʻi, ma kahi mamao o ke ahi a me nā mea ʻona.

I ka wā e hoʻolei ai i ka ʻōpala, pono e mālama ʻia nā koi hoʻoponopono kaiapuni kūpono.

 

ʻO nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o 2-formylthiazole i wehewehe ʻia ma luna.
