1,8-Octanediol(CAS#629-41-4) Hoʻomaka

ʻO 1,8-Octanediol kahi hui kino. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o 1,8-octandiol:

ʻAno maikaʻi:
ʻO 1,8-Caprylyl glycol he wai kala ʻole a me ka ʻono ʻono. He haʻahaʻa haʻahaʻa kohu a me ka viscosity ma ka lumi wela a hiki ke hoʻoheheʻe ʻia i ka wai a me ka hapa nui o nā mea hoʻoheheʻe organik.

E hoʻohana:
Loaʻa ka 1,8-Octanediol i nā mea hoʻohana. Hoʻohana pinepine ʻia e like me ka mea maka no nā softeners, plasticizers a me nā lubricants.

Hanana:
Hiki ke hoʻomākaukau ʻia ka 1,8-Octanediol ma o ka hoʻonā ʻana o ka octanol. ʻO ke ʻano hana maʻamau ka hopena catalytic oxidation o ka octanol me ka oxygen, kahi e hoʻohana pinepine ʻia ai ka copper-chromium catalyst.

ʻIke palekana:
ʻO 1,8-Octanediol kahi hui palekana ma lalo o nā kūlana maʻamau. ʻO ka ʻike ʻana a i ʻole ka inhalation o nā kiʻekiʻe kiʻekiʻe o 1,8-caprylydiol hiki ke hoʻonāukiuki i ka maka, ka ʻili, a me ka ʻōpū hanu. I ka lawelawe ʻana i ka 1,8-octanediol, pono e hoʻohana ʻia nā aniani pale, nā mīkina lima a me nā masks e hōʻoia i ka ea maikaʻi. E mālama pono e pale aku i ka hoʻopili ʻana me nā mea oxidants ikaika a me nā kumu hoʻāla e pale ai i ke ahi a pahū paha. I ka mālama ʻana a me ka mālama ʻana i ka 1,8-caprylydiol, e hahai i nā kūlana hana palekana kūpono a me nā lula.
