He aha ka ʻokoʻa ʻo Butenediol a me 1,4-Butanediol?

Butenediol a me 1,4-Butanediolʻelua mau pūhui kemika ʻokoʻa i hoʻohana ʻia i nā noi like ʻole i ka ʻoihana, lāʻau lapaʻau, a me nā ʻāpana hana. ʻOiai ko lākou mau inoa like a me ke ʻano molekala, he mau ʻokoʻa ko kēia mau pūhui ʻelua e hoʻokaʻawale iā lākou mai kekahi i kekahi.

 

ʻO ka mea mua,Butenediol a me 1,4-Butanediolloaʻa nā ʻano molekala like ʻole. Loaʻa i ka Butenediol kahi kumu, C4H6O2, aʻo 1,4-Butanediol he kumu o C4H10O2. Hoʻopili kēia ʻokoʻa i ka hoʻolālā molekala a me ke ʻano i ko lākou mau waiwai kino a me nā kemika, e like me ka hoʻoheheʻe ʻana a me ka paila ʻana, solubility, a me ka reactivity.

 

ʻO ka lua,Butenediol a me 1,4-Butanediolloaʻa nā hoʻohana a me nā hoʻohana like ʻole. Hoʻohana nui ʻia ʻo Butenediol i ka hana ʻana o ka polyester a me ka polyurethane resins, adhesives, plasticizers, a ma ke ʻano he solvent no ka pena a me nā uhi. ʻO ka hoʻohālikelike, hoʻohana ʻia ʻo 1,4-Butanediol ma ke ʻano he mea hānai no ka hana ʻana i kekahi mau kemika, me ka gamma-butyrolactone (GBL), tetrahydrofuran (THF), a me polyurethanes. Hoʻohui ʻia, hoʻohana ʻia i ka hana ʻana i nā ʻāpana automotive, electronics, pharmaceuticals, a me cosmetics.

 

ʻO ke kolu,Butenediol a me 1,4-Butanediolloaʻa nā mea ʻona a me nā pilikia e pili ana i kā lākou hoʻohana. Hoʻokaʻawale ʻia ʻo Butenediol ma ke ʻano he mea hoʻonāukiuki i ka ʻili a me nā maka a hiki ke hōʻeha i ka hanu i ka wā e inhaled ai. Ma ka ʻaoʻao ʻē aʻe, ua helu ʻia ʻo 1,4-Butanediol ma ke ʻano he carcinogen a me ka mutagen a loaʻa i kahi pilikia o ka ʻawaʻawa nui i nā kānaka inā ʻai ʻia a inhaled.

 

ʻO ka hope,Butenediol a me 1,4-Butanediolloaʻa nā kaʻina hana like ʻole. ʻO ka hana ʻana o Butenediol e pili ana i ka hopena o ka maleic anhydride me kahi waiʻona, e like me ka ethylene glycol a i ʻole propylene glycol. ʻO ka hana ʻana o 1,4-Butanediol, ma kekahi ʻaoʻao, e pili ana i ka hydrogenation o ka waikawa succinic, i loaʻa mai ka fermentation anaerobic o nā kumuwaiwai hou, e like me ka starch kulina a i ʻole ke kō.

 

I ka hopena,Butenediol a me 1,4-Butanediolʻelua pūhui kemika ʻokoʻa me nā ʻano molekala like ʻole, nā hoʻohana, nā mea ʻawaʻawa, nā pilikia, a me nā kaʻina hana. ʻOiai kaʻana like lākou i kekahi mau mea like, e like me kā lākou hoʻohana ʻana i ka hana ʻana i nā polyurethanes, loaʻa iā lākou nā waiwai kūʻokoʻa e kūpono ai no nā noi like ʻole. Pono e hoʻomaopopo i kēia mau ʻokoʻa e hōʻoia i ko lākou hoʻohana palekana a maikaʻi hoʻi i nā ʻoihana like ʻole a me nā noi.
