Hoʻolauna

ʻO 3-ethoxy-1,2-propanediol kahi mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, nā hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka waiwai:

 

ʻAno maikaʻi:

- Ke ʻano: 3-Ethoxy-1,2-propanediol he wai kala ʻole i ka wai melemele māmā.

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

 

E hoʻohana:

- Hoʻohana mau ʻia ka 3-ethoxy-1,2-propanediol e like me ka solvent a me ka waena.

- Ma muli o kona hoʻoheheʻe maikaʻi a me ka paʻa, hoʻohana nui ʻia ia i ka hoʻomākaukau ʻana i nā dyes a me nā emulsions.

 

Hanana:

Hiki ke hana ʻia ka synthesis o 3-ethoxy-1,2-propanediol e kēia mau ʻano:

- Hoʻopili ʻia ka 1,2-Propanediol me ka chloroethanol.

- Ka hopena o ka 1,2-propanediol me ka etera i ukali ʻia e ka esterification.

 

ʻIke palekana:

- Inā pili me ka ʻili a i ʻole nā ​​maka, holoi koke me ka wai nui.

- Pono e mālama ʻia i loko o kahi pahu paʻa i ka ea, ma kahi mamao aku i ka ignition a me nā oxidizer, e pale aku i ka pilikia o ke ahi a me ka pahū.

- E hahai i nā hana hoʻokolohua maikaʻi a hoʻohana i nā lako pale pilikino kūpono i ka wā e hoʻohana ai.
