Intshayelelo
I-1,9-i-Nonanediol yi-diol ene-athomu ze-carbon ezilithoba. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-1,9-nonanediol:
Umgangatho:
I-1,9-Nonanediol iqinile kunye neekristale ezimhlophe kwiqondo lokushisa. Ineempawu zokungabi nambala, azinavumba, kwaye zinyibilika kwizinyibilikisi zendalo ezifana namanzi, iether, kunye neacetone. Yikhompawundi engaguquguqukiyo kwaye inetyhefu ephantsi.
Sebenzisa:
I-1,9-Nonanediol inezicelo ezininzi kwishishini lemichiza. Ingasetyenziswa njenge-solvent kunye ne-solubilizer, kwaye ingasetyenziselwa amayeza, idayi, i-resin, iingubo, iiplastiki kunye namanye amashishini. Ineempawu ezilungileyo ze-surfactant kwaye ingasetyenziswa njenge-emulsifier, i-agent yokumanzisa kunye nokuzinzisa.
Indlela:
Kukho iindlela ezininzi zokulungiselela i-1,9-nonanediol, kwaye enye yeendlela eziqhelekileyo ezisetyenziswayo yi-synthesis evela kwi-hydrogenation reaction of nonanal. I-Nonanal iphendula kunye ne-hydrogen phambi kwe-catalyst ukuvelisa i-1,9-nonanediol.
Ulwazi ngoKhuseleko:
I-1,9-i-Nonanediol ine-toxicity ephantsi kwaye ikhuselekile kusetyenziso lwamashishini. Njengemichiza, le miqathango yokhuseleko ilandelayo kusafuneka iqatshelwe:
- Kuphephe ukudibana nolusu kunye namehlo. Kwimeko yoqhagamshelwano, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye udibane nodokotela.
- Ngexesha lokusetyenziswa, umoya olungileyo kufuneka usetyenziswe ukuphepha ukuphefumla iigesi okanye umphunga.
- Xa ugcina kwaye uphatha, kufuneka ukhuselwe ekudibaneni ne-oxidants kunye nezinto ezinamandla ezixutywayo ukuphepha umlilo okanye ukuqhuma.
- Nxiba izixhobo ezifanelekileyo zokuzikhusela ezifana neeglavu, iiglasi, kunye nempahla yokuzikhusela ngexesha lokusetyenziswa.
