Hoʻolauna

ʻO ka FEMA 3148 he hui lāʻau me ke kumu hoʻohālike kemika C12H22O2. He wai waihoʻoluʻu me ka ʻono strawberry ʻono. Eia ka wehewehe ʻana o ke ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana o FEMA 3148:

 

ʻAno:

-Nani: wai kala ʻole

-Molecular kaumaha: 194.3g/mol

-Ka helu heheʻe:-57 ° C

-Pila paila: 217 ° C

-Ka mānoanoa: 0.88g/cm³

-Solubility: ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe iki i ka waiʻona

 

E hoʻohana:

- Hoʻohana pinepine ʻia ʻo FEMA 3148 i nā mea ʻala a me nā mea hoʻohui meaʻai e hoʻomaikaʻi ai i ka strawberry, nā mea kanu a me ka ʻono ʻala.

-Eia kekahi, hiki ke hoʻohana ʻia e synthesize i nā mea hoʻohui ʻē aʻe, e like me nā solvents Ester, nā uhi a me nā mea hoʻohui plastik, etc.

 

Kaʻina hoʻomākaukau:

Hoʻohana maʻamau ke ʻano hoʻomākaukau o FEMA 3148 i kēia mau ʻanuʻu:

1. Me ka hoʻohana ʻana i ka waikawa adipic ma ke ʻano he mea maka, ua hana ʻia ka hexanol hexanoate e ka hopena transesterification o ka waiʻona.

2. Hoʻokomo ʻia ka ester ʻakika caproic i loaʻa i ka hopena condensation dehydration i mua o kahi mea hoʻoheheʻe waika ikaika e hana ai i ka FEMA 3148.

 

ʻIke palekana:

- FEMA 3148 maʻamau he haʻahaʻa loa ka ʻona ma lalo o nā kūlana maʻamau o ka hoʻohana.

-He wai wela ia, pono e mālama ʻia mai ke ahi a me ka wela kiʻekiʻe, a mālama ʻia i loko o kahi anuanu a maikaʻi.

-pono ka hoʻohana ʻana e pale aku i ka pili ʻana me ka ʻili a me nā maka, e like me ka hoʻopā ʻana, pono e holoi koke me ka wai nui.

- ma ka hoʻohana ʻana i ke kaʻina hana pono e hoʻolohe i nā hana pale, e komo pū me nā mīkina lima, e hoʻokomo i nā lole pale kūpono a me nā aniani pale. Pono e hoʻomaʻemaʻe maikaʻi ʻia ka wahi hana ma hope o ka hana.
