Izicelo Ezijwayelekile

Ukuguquguquka kwe-solvent ye-Isopropyl Ether kanye nokuguquguquka kwayo kwenza kube yinto ebalulekile emikhakheni eminingi:

3.1 Ukwenziwa Kwamakhemikhali Nokukhishwa

Ukwenziwa Kwezinto Eziphilayo: Kusebenza njengesinyibilikisi sokusabela se-Grignard reactions, alkylations, kanye ne-esterifications. I-polarity yayo ephansi isiza ukulawula amazinga okusabela futhi ithuthukise isivuno somkhiqizo wezinto eziphakathi ezingezona eziphansi.

Ukukhishwa Koketshezi Oluyi-Liquid: Kusetshenziselwa ukuhlukanisa amakhemikhali e-organic ezixazululweni zamanzi (isb., ukukhipha imithi, izibulala-zinambuzane, noma amakhemikhali anongwe kusuka ku-fermentation broths noma ezikhishwe ezitshalweni).

Ukukhiqizwa kwe-Peroxide: Isebenza njengezinto zokusetshenziswa zokukhiqiza i-diisopropyl peroxydicarbonate (IPP), okuyisiqalisi esivamile sokwenziwa kwe-polymer (isb., i-polyvinyl chloride, i-PVC).

3.2 Ukuhlanza Nokumboza Izimboni

I-Degreasing Agent: Isebenza kahle ekususeni uwoyela, amafutha, kanye ne-wax ezingxenyeni zensimbi (isb., izingxenye zezimoto, imishini) ngenxa yokuthi inamandla kakhulu kuma-hydrocarbon.

Ukwakheka Kokumboza Nokunamathela: Kunciphisa ama-resins, ama-lacquers, kanye nezinamathiselo ukuze kulungiswe i-viscosity, kuqinisekiswe ukusetshenziswa okubushelelezi kanye nokuqiniswa okusheshayo (okusetshenziswa ezimbozweni zokhuni, ezinamathiselweni zezimboni).

3.3 Ukusetshenziswa Kwelebhu Nokuhlaziya

I-Chromatography Solvent: Isetshenziswa njengengxenye yesigaba esihambayo ku-gas chromatography (GC) kanye ne-high-performance liquid chromatography (HPLC) yokuhlukanisa ama-organic analytes.

Isinyibilikisi Sokulungiselela Isampula: Sincibilikisa amasampula aqinile (isb., ama-lipid, ama-polymer) ukuze kuhlaziywe ngamakhemikhali (isb., i-Fourier-transform infrared spectroscopy, i-FTIR).

3.4 Uphethiloli kanye Namandla

Isengezo Sikaphethiloli: Sihlanganiswe nophethiloli ukuthuthukisa izinga le-octane nokunciphisa ukugoba kwenjini; futhi sithuthukisa ukuzinza kukaphethiloli ngesikhathi sokugcina.

Ukuphepha Nokuthobela

4.1 Iziqondiso Zokuphepha

Ingozi Yokusha: Uketshezi kanye nomhwamuko ovutha kakhulu; gcina kude namalangabi avulekile, izinhlansi, kanye nezindawo ezishisayo (sebenzisa imishini engaqhumi ezindaweni zokuphatha).

Ukwakheka kwe-Peroxide: Kungakha ama-peroxide aqhumayo uma evezwa emoyeni, ekukhanyeni, noma ekushiseni ngokuhamba kwesikhathi. Hlola ama-peroxide (usebenzisa iphepha le-starch-iodide) ngaphambi kokusebenzisa; lahla uma kutholakala ama-peroxide.

Izinto Zokuvikela Zokuphatha: Gqoka amagilavu e-nitrile, izibuko zamakhemikhali ezisebenzisa amakhemikhali, kanye nomshini wokuphefumula ngomusi (N95 noma ngaphezulu) ezindaweni ezingangenisi umoya kahle. Gwema ukuxhumana kwesikhumba/namehlo (kungabangela ukucasuka) kanye nokuhogela umusi (kungabangela isiyezi noma isicanucanu).

Indawo Yokugcina: Gcina endaweni epholile, emnyama, enomoya omuhle; sebenzisa izitsha zengilazi ephuzi noma ze-HDPE ezingangeni moya. Faka i-peroxide inhibitor (isb. i-hydroquinone) ukuze ugcine isikhathi eside.

4.2 Ukuthobela Imithetho

I-REACH (EU): Ibhaliswe ngaphansi kwe-REACH (Inombolo Yokubhalisa: 01-2119488787-46-xxxx); ihambisana nemikhawulo yokungcola kwe-peroxide.

I-OSHA (US): Umkhawulo Wokuchayeka Emsebenzini (OEL): 500 ppm (i-TWA yamahora angu-8); ehlukaniswe njengoketshezi oluvuthayo (i-NFPA Class IB).

Ukuhlukaniswa kwe-GHS: GHS02 (Uketshezi Oluvuthayo), GHS07 (Okucasulayo), GHS08 (Kungase kwakheke ama-peroxide aqhumayo).

Izindinganiso ze-ISO: Ihlangabezana ne-ISO 6353-2 (izincazelo zebanga le-Reagent) ukuze isetshenziswe elebhu.

Okuvelele kweShedi Ledatha Lobuchwepheshe (i-TDS)

Ipharamitha	Ibanga Lezimboni	Ibanga le-Reagent	Indlela Yokuhlola
Ubumsulwa (iminithi)	99.0%	99.5%	I-Gas Chromatography (GC)
Okuqukethwe komswakama (okuphezulu)	0.1%	0.05%	UKarl Fischer Titration
Okuqukethwe kwe-Peroxide (okuphezulu)	5 ppm	1 ppm	I-Iodometric Titration
I-asidi (njenge-CH₃COOH, ubuningi)	0.005%	0.001%	Ukulinganiswa kwe-Sodium Hydroxide
Izinsalela Ezingaguquguquki (ubuningi)	5 mg/kg	1 mg/kg	I-Gravimetry

Kungani Kufanele Ukhethe I-Isopropyl Ether Yethu (CAS 108-20-3)?

Ingozi Ephansi Ye-Peroxide: Umkhiqizo wethu uqiniswa ngezithiyo zokudla, okunciphisa ukwakheka kwe-peroxide nokuqinisekisa ukusetshenziswa okuphephile.

Ukuhlanzeka Okuqhubekayo: Ukulawulwa kokuhlanzeka kwe-batch-to-batch (≥99.0% yezinga lezimboni) kunciphisa ukungcola okuphazamisa izinqubo.

Ukupakisha Okwenziwe Ngokwezifiso: Kutholakala ngama-drum angu-1L, 20L, 200L, noma amathangi e-ISO kuma-oda amancane e-实验室 noma ezimbonini eziningi.

Usekelo Lobuchwepheshe: Ithimba lethu linikeza isiqondiso ngokuhlolwa kwe-peroxide, ukugcinwa, kanye nokwenza ngcono ukusetshenziswa kwayo (isb., ukuxuba i-solvent ukuze ikhishwe).

Ukuthobela Umthetho Komhlaba Wonke: Kuhlangabezana nezindinganiso zamazwe ngamazwe (i-REACH, i-OSHA, i-ISO) ukuze zisetshenziswe ezimakethe ze-EU, i-US, kanye ne-Asia.
