Umhlaba wonkhe - Tjwala Be-Isopropyl Lobuyinhloko: I-Compawundi Yetilwane Lenetincenye Letinyenti

Timphahla Letibonakalako Netemakhemikhali

Kubukeka Neliphunga: Kuyintfo lesemantini lebonakalako lete umbala leneliphunga lelifana ne-ethanol.
Kuncibilika: Ingahlanganiswa nemanti, i-ethanol, i-ether, i-acetone, kanye naletinye tintfo letiphilako.
Letinye Timphahla: Sikhulu sayo se molar ngu 60.10 g/mol, bukhulu bayo ngu 0.786 g/mL (ku 25°C), indzawo yekuncibilika ngu - 89.5°C, bese indzawo yekubila ngu 82.3°C. Iphuzu lokukhanya lingu 11.7°C.

Tindzawo Tekufaka Sicelo

Sincibilikisi: Isebenta njengesincibilikisi lesihle kakhulu se shellac, i-nitrocellulose, i-alkaloids, irabha, emafutsa, njll Iphindze isetjentiswe ekwakhiweni kwetibulala tinambuzane kanye netintfo tekuhlanta ingilazi. Ngekwengeta, ingasebenta njengentfo lekhipha emafutsa e cottonseed kanye netinongo.

Tintfo letiluhlata embonini yemakhemikhali laphilako: Ngekuphendvula lokuhlukahlukene, ingakhicita imikhicito leyehlukahlukene yemakhemikhali lefana ne isopropylamine, i-methyl isobutyl ketone, i-methyl isobutyl carbinol, njll.

Insimu Yemitsi: Kuyintfo leluhlata yekukhicita imitsi lefana ne Propranolol, Rifampicin, Pindolol, Diisopropylamine Dichloroacetate, njll Ingasetjentiswa kukhipha emavithamini kanye nekuhlanta emakhepsuli emitsi. Ngalokuvamile isetjentiswa njengesibulalimagciwane esikhumbeni, tintfo tekufakelwa, kanye netintfo tekwelapha, futsi ingaphindze futsi isetjentiselwe kulondvolota tibonelo tetilwane.

Insimu Yemboni Ye-Elekthronikhi: High - ubumsulwa isopropyl tjwala isetjentiswa njenge ejenti kuhlanta kanye etchant ngesikhatsi umkhicito semiconductor tincenye kanye nekuhlangana kanye nekucubungula lokukhulu kakhulu - sikali emasekhethi lahlanganisiwe. Ingaphindze isetjentiswe njenge-ejenti yekuhlanta lekhipha emafutsa ensimbi.

Insimu Yetimoto: Njengesengeto sephethiloli, kungakhulisa inombolo ye-octane yaphethiloli, kwenta ncono lizinga laphethiloli. Ingaphindze isetjentiswe njengekuhlanta ingilazi yetimoto, i-deicer yetingilazi temoya, kanye ne anti - fogging agent ye aerosol - luhlobo lwetingilazi temoya.

Tindlela Tekulungiselela

Kufaka emanti ePropylene: Kwanyalo, i-hydration lecondzile ye-propylene yindlela leyinhloko. Ngaphansi kwesento se catalyst, ipropylene ihlangana ngco nemanti ngekuhlangana kwekwengeta kwentela kukhicita tjwala be isopropyl. Ngekuya kwesimo sesigaba se-reactants, ingahlukaniswa ibe yindlela yesigaba segesi, igesi - indlela yesigaba lesihlanganisiwe keketshezi, kanye nendlela yesigaba seketshezi.

Kuhlanganiswa kwe-Acetone: Ngaphansi kwesento sesikhutsato, i-acetone incishiswa ibe tjwala be-isopropyl emkhatsini we-hydrogen. Lendlela inekushisa lokuphansi kwekuphendvula, umfutfo lojwayelekile, kusetjentiswa kwemandla lokuphansi, kugeleta kwenchubo lelula, kanye nekugcola lokuncane kakhulu kumishini.

Kufakwa kwemanti e-Isopropyl Acetate: Ngaphansi kwesento sesikhutsati, i-isopropyl acetate ifakwa emanti kwentela kukhicita ngasosonkhe sikhatsi tjwala be-isopropyl kanye ne-ethanol. Nomakunjalo, kunemikhicito leminyenti lehambisanako, futsi kwehlukaniswa kwe ethanol kanye ne isopropyl alcohol kumatima, ngako akukasetjentiswa kakhulu.

Tinyatselo tekuvikela

Umhwamuko we isopropyl alcohol uyacasula emehlweni nesikhumba, futsi kuphefumula kungaba nebuthi. Ingeyesigaba 3 semdlavuza. Lapho bantfu baphefumula lokuhlukene kwe-isopropyl alcohol, batawuba nekuphendvula lokuhlukile. Sibonelo, ku 400 ppm, kutawubangela kutfukutsela lokuncane emehlweni, emphumulweni, nasemphinjeni, kantsi ku 20000 ppm, kutawuvele kubeke engotini imphilo noma imphilo.

Tjwala be-isopropyl buyavutsa. Umhwamuko wayo ungakha umhlanganiso loqhumako nemoya. Kungabangela kuvutsa kanye nekuqhuma uma kuvulekile emalangabini kanye nekushisa lokusetulu. Kufanele igcinwe endzaweni lepholile futsi lenemoya, khashane nemitfombo yemlilo kanye nemitfombo yekushisa, ivikelwe ekukhanyeni kwelanga lokucondzile, futsi lesitja kumele sigcinwe sivaliwe. Kufanele igcinwe ngekwehlukana kuma oxidants.
