Hoʻolauna

Methyl thioethyl S-acid branyl. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka methyl thioethyl thioS-acid furfur:

 

ʻAno maikaʻi:

ʻO ka Methyl thioethyl S-fufrate he wai kala ʻole me kahi ʻono methyl sulfate kūikawā. Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me nā ʻona, nā ketones, a me nā ethers, akā hiki ʻole ke hoʻoheheʻe ʻia i ka wai.

 

E hoʻohana:

Hoʻohana nui ʻia ka Methyl thioethyl S-furfur i ke kahua o ka synthesis organik. Hiki ke hoʻohanaʻia e like me ka reagent no nāʻano likeʻole o ka synthesis reactions, e like me ka carbonylation o nā amines, ka esterification a me ka acylation o nā waiʻona, a me nā mea'ē aʻe.

 

Hanana:

ʻO ka hoʻomākaukau ʻana o ka methyl thioethyl S-acid furfur e loaʻa pinepine ʻia e ka hopena o ka carbon disulfide me ka methyl chloroacetate. ʻO ke ʻano o ka hoʻomākaukau ʻana penei: hoʻokuʻu mālie ʻia ke kalapona disulfide i loko o ka methyl chloroacetate i loko o ka wai hau, a hoʻoulu ʻia ka hopena hopena i ka manawa like. Ma hope o ka pau ʻana o ka hopena, hoʻohui ʻia ka hopena hopena i ka solution sodium chloride saturated, a laila lawe ʻia ka papa organik a maloʻo me ka sodium chloride anhydrous. Loaʻa ka Methyl thioethyl S-acid furfur ma ka distillation.

 

ʻIke palekana:

ʻO ka Methyl thioethyl S-furfur he mea hoʻoheheʻe kūlohelohe me ka ʻala ʻala a pono e pale ʻia ke hoʻohana ʻia. I ka hana ʻana, pono e hoʻohana ʻia nā mea pale kūpono e like me nā aniani pale a me nā mīkina lima. Pono e mālama ʻia ma kahi ʻoluʻolu, maloʻo, maikaʻi-ventilated, ma kahi mamao o ka ignition a me nā oxidizers, e pale aku i ke ahi a me ka pahū. No ka hoʻohana ʻana a me ka mālama ʻana i nā kemika, pono e hahai i nā hana mālama pono.
