Isopropyl Ether yinhlanganisela ye ether levutsako, levutsako leyatiwa kakhulu ngetimphahla tayo letinhle kakhulu tekuncibilikisa. Njenge solvent lesemkhatsini we polarity, ilinganisa kuncibilika kwatotimbili tintfo letiphilako kanye ne polar kancane, kwenta kutsi kube yintfo lebalulekile ekuhlanganiseni emakhemikhali, kukhipha, kanye nekuhlanta etimbonini. Liphuzu layo leliphansi lekubila kanye nekugucugucuka lokulinganiselwe nako kwenta kutsi kubelula kululama etinchubeni tekuvubela, kusekela kusebenta kahle kwetindleko kanye nekusimama.

Ticelo letijwayelekile
Isopropyl Ether's solvent kusebenta ngetindlela letinyenti kanye nekungagucugucuki kwenta kutsi kube yintfo ledzingekako kuyo yonkhe imboni leminyenti:
3.1 Kuhlanganiswa kwemakhemikhali & Kukhishwa
Kuhlanganiswa kwetintfo letiphilako: Kusebenta njengesincibilikisi sekuphendvula kwekuphendvula kwe Grignard, ema alkylations, kanye ne esterifications. I-polarity yayo lephansi isita kulawula emazinga ekuphendvula kanye nekutfutfukisa umkhicito wetintfo letisemkhatsini letingekho e-polar.
Kukhipha Lokusamanti-Kusamanti: Kusetjentiswa kwehlukanisa emakhompawundi etilwane kusuka etisombululweni letinemanti (sib., kukhipha imitsi, tibulala tilwane, noma emakhompawundi ekunambitseka kusuka kumhluti wekuvubela noma tintfo letikhishwako tetitjalo).
Kukhicita iPeroxide: Isebenta njengentfo leluhlata yekukhicita iDiisopropyl peroxydicarbonate (IPP), umsunguli lovamile wekuhlanganiswa kwe polymer (sib., i-polyvinyl chloride, iPVC).
3.2 Kuhlanta Timboni Nekugcobisa
Degreasing Agent: Isebenta kahle ekususeni oyili, emafutsa, kanye ne wax etincenyeni tensimbi (sib., tincenye tetimoto, imishini) ngenca yekuncibilika kwayo lokucinile kwema hydrocarbons.
Kugcobisa & Kunamatsela: Kunciphisa ema resin, ema lacquers, kanye nekunamatsela kwentela kulungisa viscosity, kucinisekisa kusetjentiswa lokubushelelezi kanye nekuphola lokusheshako (kusetjentiswa ekugcokeni kwetigodvo, kunamatsela kwetimboni).
3.3 Kusetjentiswa Kwelabhorethri Nekuhlatiya
Sisombululi se Chromatography: Sisetjentiswa njengencenye yesigaba lesihambako ku chromatography yegesi (GC) kanye ne chromatography lesetulu lesemantini (HPLC) yekuhlukanisa tintfo letihlatiyako letiphilako.
Sincibilikisi Sekulungiselela Sampula: Sincibilikisa emasampula lacinile (sib., emafutsa, emapholymer) ekuhlatiya emakhemikhali (sib., i-Fourier-yekugucula i-spectroscopy ye-infrared, i-FTIR).
3.4 Emafutsa etitfutsi nemandla
Fuel Additive: Ihlanganiswe naphethiloli kwenta ncono silinganiso se-octane kanye nekunciphisa kungcondvo kwenjini; iphindze ikhulise kusimamisa kwaphethiloli ngesikhatsi sekugcina.
Kuphepha & Kulandzela
4.1 Imihlahlandlela Yekuphepha
Ingoti Yekuvutsa: Kuvutsa kakhulu kanye nemphunga; gcina khashane nemalangabi lavulekile, tinhlansi, kanye netindzawo letishisako (sebentisa tintfo letingaqhumi etindzaweni tekuphatsa).
Kubunjwa kwe Peroxide: Kungakha ema peroxides laqhumako uma ahlangene nemoya, kukhanya, noma kushisa ngekuhamba kwesikhatsi. Hlola ema peroxides (kusebentisa liphepha lesitashi-iodide) ngaphambi usebentise; lahla uma kutfolakala ema peroxides.
Kuphatsa Tintfo Tekuvikela: Gcoka emagilavu e-nitrile, tibuko tekufafata emakhemikhali, kanye nesiphefumulo semhwamuko (N95 noma ngetulu) etindzaweni letingangenisi umoya kahle. Gwema kutsintsana nesikhumba/emehlo (kungabangela kutfukutsela) kanye nekuphefumula umhwamuko (kungabangela kushaywa siyeti noma kucansuka).
Kugcina: Gcina endzaweni lepholile, lemnyama, lefaka umoya kahle; sebentisa titja letingangeni moya, ingilazi le-amber noma i-HDPE. Faka sivimbeli se-peroxide (sib., i-hydroquinone) kwentela kugcina sikhatsi lesidze.
4.2 Kulandzela Umtsetfo
KUFINYELA (EU): Kubhalisiwe ngaphansi kweKUFINYELA (Inombolo Yekubhalisa: 01-2119488787-46-xxxx); kuhambisana nemikhawulo yekungcola kwe-peroxide.
OSHA (US): Umkhawulo Wekuchayeka Emsebentini (OEL): 500 ppm (TWA yemahora langu-8); kuhlukaniswe njengentfo levutsako (NFPA Lizinga IB).
GHS Kuhlukaniswa: GHS02 (Ludzaka Loluvutsako), GHS07 (Lokucasulako), GHS08 (Kungakha ema-peroxides laqhumako).
Emazinga e-ISO: Ahlangabetana ne-ISO 6353-2 (Tincazelo telibanga le-Reagent) tekusetjentiswa elabhorethri.
Liphepha Lemininingwane Yebuchwepheshe (TDS) Tintfo Letigcamile

Kungani Sikhetsa I-Ether Yetfu Ye-Isopropyl (CAS 108-20-3)?
Ingoti Lephansi Ye Peroxide: Umkhicito wetfu uciniswa ngetivimbeli telizinga lekudla, kunciphisa kwakheka kwe peroxide kanye nekucinisekisa kusetjentiswa lokuphephile.
Kuhlanteka Lokungagucuki: Kulawula kuhlanteka kwe Batch kuya ku batch (≥99.0% yesigaba setimboni) kunciphisa kungcola lokuphazamisa tinchubo.
Kupakisha Lokwentiwe Ngendlela Lefanele: Kutfolakala ngetigubhu te-1L, 20L, 200L, noma emathangi e-ISO e-实验室 lamancane noma ema-oda lamanyenti etimbonini.
Kusekelwa Kwebuchwepheshe: Licembu letfu liniketa sicondziso ngekuhlolwa kwe peroxide, kugcina, kanye nekusebenta kahle kwesicelo (sib., kuhlanganiswa kwetinhlayiya tekukhipha).
Kuhambisana Kwemhlaba Wonkhe: Kuhlangabetana nemazinga emhlaba wonkhe (REACH, OSHA, ISO) kutsi asetjentiswe etimakethe te-EU, US, nase-Asia.
