Propylene oxidehe wai waihoʻoluʻu a ʻākala me ke kumu molekala o C3H6O. Hiki ke hoʻoheheʻe ʻia i loko o ka wai a he 94.5°C kona wahi e hoʻolapalapa ai. ʻO ka propylene oxide kahi mea kemika hoʻoheheʻe e hiki ke hana me ka wai.

Epoxy propane hale kūʻai

Ke hoʻopili ʻia ka propylene oxide i ka wai, e hana ʻia ka hopena hydrolysis e hana i ka propylene glycol a me ka hydrogen peroxide. Penei ka hoohalike pane.

 

C3H6O + H2O → C3H8O2 + H2O2

 

He exothermic ke kaʻina hana, a hiki i ka wela i hana ʻia ke piʻi wikiwiki ka mahana o ka hopena. Eia kekahi, he mea maʻalahi hoʻi ka propylene oxide i ka polymerize i mua o nā catalysts a i ʻole ka wela, a ʻaʻole hiki ke hoʻoheheʻe ʻia nā polymers i hana ʻia i ka wai. Hiki i kēia ke alakaʻi i ka hoʻokaʻawale ʻana a hoʻokaʻawale ka wai mai ka ʻōnaehana pane.

 

Hoʻohana ʻia ka propylene oxide ma ke ʻano he kumu no ka synthesis o nā huahana like ʻole, e like me nā surfactants, lubricants, plasticizers, etc. synthesis, pono e mālama pono a lawe ʻia ka propylene oxide e pale aku i ka pili ʻana me ka wai e pale aku i nā pōʻino palekana.

 

Eia kekahi, hoʻohanaʻia ka propylene oxide i ka hanaʻana i ka propylene glycol, he mea koʻikoʻi ia no ka hanaʻana i ka fiber polyester, film, plasticizer, etc. ka mea e pono e hoomalu pono ia i ka hana hana e pale aku i ka pili ana me ka wai e pono ai ka hana pono.

 

I ka hōʻuluʻulu ʻana, hiki i ka propylene oxide ke hana me ka wai. Ke hoʻohana nei i ka propylene oxide ma ke ʻano he mea maka no ka synthesis a i ke kaʻina hana, pono e hoʻolohe i kāna mālama palekana a me ka lawe ʻana e pale aku i ka hoʻopili ʻana me ka wai a me nā pōʻino palekana.
