Nhanganyaya

1,1-Dichloro-2,2-difluoroethylene, inozivikanwawo seCF2ClCF2Cl, is an organic compound. Iyi inotevera sumo kune chimiro chayo, kushandiswa, nzira yekugadzirira uye ruzivo rwekuchengetedza:

 

Hunhu:

1,1-Dichloro-2,2-difluoroethylene imvura isina ruvara ine kunhuhwirira kwakasiyana. Iyo yakaoma uye haina kunyungudika mumvura, asi inogona kunyungudika mune zvakawanda organic solvents.

 

Shandisa:

1,1-Dichloro-2,2-difluoroethylene ine zvakasiyana-siyana zvekushandisa mumakemikari indasitiri. Chinhu chakakosha chekunyungudutsa chinoshandiswa zvakanyanya kunyungudutsa kana kunyungudutsa akawanda organic compounds. Inoshandiswawo sefiriji uye refrigerant, uye inoshandiswa kugadzira fluoroelastomers, fluoroplastics, lubricant, uye optical materials, pakati pezvimwe. Muindasitiri yemagetsi, inoshandiswawo sechinhu chakabikwa chekuchenesa vamiririri uye zvinhu zvine yakakwira dielectric inogara.

 

Nzira:

Kugadzirira kwe1,1-dichloro-2,2-difluoroethylene inowanzowanikwa nekuita 1,1,2-trifluoro-2,2-dichloroethane nemhangura fluoride. Mhedzisiro yacho inoitwa pakupisa kwakanyanya uye pamberi peiyo catalyst.

 

Zvekuchengetedza

1,1-Dichloro-2,2-difluoroethylene chinhu chine njodzi, uye kuratidzwa kana kufemerwa nemhute yaro kunogona kukonzera ziso, kufema uye kutsamwa kweganda. Kuratidzwa kune yakanyanya kuwanda kunogona kukonzera kukanganisa kune yepakati tsinga system nemapapu. Matanho anodiwa ekuchengetedza anofanirwa kutorwa panguva yekushandiswa, sekupfeka midziyo yekudzivirira yakakodzera, kuona mhepo yakanaka, nezvimwewo. Mushonga unofanirwa kuchengetedzwa zvakanaka uye kuraswa kudzivirira kusvibiswa kwezvakatipoteredza.
