Hoʻolauna

R-(+) tetrahydrofuranoic acid. ʻO kēia ka hoʻolauna ʻana i kekahi o nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o R-(+)tetrahydrofuranoic acid:

 

ʻAno maikaʻi:

- R-(+)tetrahydrofuranoic acid he paʻa waihoʻoluʻu a ʻeleʻele melemele me kahi ʻono ʻawaʻawa.

- Hoʻoheheʻe ia i loko o ka wai a ʻike ʻia e like me ka wai me ka hoʻololi ʻana i ka optical ma kahi mahana wela.

- Hiki iā ia ke hana me nā pūhui ʻē aʻe e like me ka esterification, condensation, reduction, etc.

 

E hoʻohana:

- Hoʻohana pū ʻia ʻo R-(+)tetrahydrofuranoic acid i ka hoʻomākaukau ʻana i nā mea hoʻohui ʻē aʻe, e laʻa i ka synthesis o nā plastic biodegradable e like me ka polylactic acid.

 

Hanana:

- Hiki ke hoʻomākaukau ʻia ka waikawa R-(+)tetrahydrofuranoic e nā ʻano hana like ʻole e like me ka hoʻokaʻawale ʻana o ka optical, ka hoʻemi kemika, a me nā ʻano enzymatic.

- ʻO ka hoʻokaʻawale Optical kahi ʻano hoʻomākaukau maʻamau e hoʻokaʻawale i nā isomer ʻē aʻe o D-lactate ma ke koho ʻana i nā microorganism a i ʻole nā ​​enzyme kūpono.

 

ʻIke palekana:

- R-(+)tetrahydrofuranoic acid ka palekana ma lalo o nā kūlana hoʻohana maʻamau.

- Hiki i ka pili lōʻihi ke hoʻonāukiuki i ka ʻili a me nā maka, a pono e mālama i ka wā e lawelawe ai.

- I ka mālama ʻana a me ka mālama ʻana, pono e mālama pono ʻia nā kaʻina hana palekana kūpono, a e pale ʻia ka launa pū ʻana me nā mea oxidizing ikaika a me nā mea hiki ke ahi.
