Hoʻolauna

ʻO 1,1-Dichloro-2,2-difluoroethylene, i ʻike ʻia ʻo CF2ClCF2Cl, he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, ʻano hoʻomākaukau a me ka ʻike palekana:

 

ʻAno maikaʻi:

ʻO 1,1-Dichloro-2,2-difluoroethylene he wai kala ʻole me kahi ʻala ʻokoʻa. ʻOi aku ka paʻa a hiki ʻole ke hoʻoheheʻe ʻia i ka wai, akā hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik.

 

E hoʻohana:

Loaʻa i ka 1,1-Dichloro-2,2-difluoroethylene nā ʻano hana like ʻole i ka ʻoihana kemika. He mea hoʻoheheʻe koʻikoʻi i hoʻohana nui ʻia e hoʻoheheʻe a hoʻoheheʻe paha i nā pūhui organik he nui. Hoʻohana ʻia ia e like me ka refrigerant a me ka refrigerant, a hoʻohana ʻia e hana i nā fluoroelastomers, fluoroplastics, lubricants, a me nā mea optical, a me nā mea ʻē aʻe. I ka ʻoihana uila, hoʻohana ʻia ia ma ke ʻano he mea maka no ka hoʻomaʻemaʻe ʻana i nā mea hana a me nā mea me ka dielectric mau.

 

Hanana:

ʻO ka hoʻomākaukau ʻana o 1,1-dichloro-2,2-difluoroethylene ka mea maʻamau e loaʻa ma ka reacting 1,1,2-trifluoro-2,2-dichloroethane me ka fluoride keleawe. Hoʻokō ʻia ka hopena ma nā wela kiʻekiʻe a ma ke alo o kahi catalyst.

 

ʻIke palekana:

He mea weliweli ka 1,1-Dichloro-2,2-difluoroethylene, a ʻo ka ʻike ʻana a i ʻole ka inhalation o kona mau mahu e hoʻonāukiuki i ka maka, ka hanu a me ka ʻili. ʻO ka ʻike ʻia ʻana i nā haʻahaʻa kiʻekiʻe e hōʻino paha i ka ʻōnaehana nīnū waena a me nā māmā. Pono e mālama ʻia nā hana palekana i ka wā e hoʻohana ai, e like me ke komo ʻana i nā mea pale kūpono, e hōʻoia i ka ea maikaʻi, a me nā mea ʻē aʻe.
