Isopropyl Ether ni imvange ya ether ihinduka kandi ishobora gushya izwi cyane kubera imiterere yayo myiza yo gushonga. Nk'umusemburo wa polarity yo hagati, ihuza gushonga kw'ibintu bya organic n'ibice bito, bigatuma iba ingenzi mu gukora imiti, kuyikuramo, no kuyisukura mu nganda. Ishyuha cyane kandi ihindagurika buhoro buhoro nabyo bituma byoroha kuyigarura mu buryo bworoshye mu mikorere yo gushonga, bigafasha mu gukoresha neza ikiguzi no kuramba.
Imiterere n'Ibyiza by'ingenzi
| Umutungo | Ibisobanuro | Akamaro k'ingenzi |
| Gushonga | Ishonga gato mu mazi (~1.2 g/L kuri 20°C); ishobora kuvangwa na ethanol, acetone, benzene, n'ibindi bintu byinshi bishongesha ibinyabuzima | Ikoreshwa mu gushonga amavuta, resins, waxes, n'ibindi binyabutabire by'umwimerere; ijyanye n'ibintu bisanzwe bisukura |
| Guhindagurika kw'ikirere | Umuvuduko w'umwuka: 16.9 kPa kuri 20°C; ubushyuhe buke (68 - 69°C) | Bituma habaho guhumeka vuba mu buryo bwo gusiga/kumisha; byoroshye gutandukanya hakoreshejwe uburyo bwo gukaraba |
| Guhagarara kw'ibinyabutabire | Irahamye mu gihe gisanzwe cyo kubika; ibora buhoro buhoro iyo ihuye na aside ikomeye cyangwa peroxide | Yizewe kubikwa igihe kirekire (iyo irinzwe na peroxide); igabanya cyane ingaruka ku bintu byinshi |
| Ubucucike (20°C) | 0.725 g/cm³ | Ubucucike buke bugabanya ikiguzi cyo gutwara; byoroshye kubikemura mu buryo bwo kuvanga amazi |
| Ubushyuhe bwo kwiyatsa | Ubushyuhe bugera kuri 443°C (829°F) | Bifite umutekano kurusha imiti ishobora gushya cyane (urugero: diethyl ether) mu bidukikije bigenzurwa |
Porogaramu zisanzwe
Uburyo bworoshye bwo gushonga bwa Isopropyl Ether n'uburyo ihindagurika mu mikorere yayo bituma iba ingenzi mu nganda nyinshi:
3.1 Gutunganya no Gukuramo Ibinyabutabire
Gukora Organic Synthesis: Ikora nk'umusemburo w'ibisubizo bya Grignard, alkylations, na esterifications. Polarity yayo nke ifasha kugenzura igipimo cy'ibisubizo no kunoza umusaruro w'ibicuruzwa ku bisubizo bitari polar.
Gukuramo amazi n'ibinyabutabire: Bikoreshwa mu gutandukanya ibinyabutabire by'umwimerere n'ibinyabutabire by'amazi (urugero: gukuramo imiti, imiti yica udukoko, cyangwa ibinyabutabire by'uburyohe mu mufa w'ibinyabutabire cyangwa ibinyabutabire by'ibimera).
Gukora Peroxide: Ikora nk'ibikoresho fatizo byo gukora diisopropyl peroxydicarbonate (IPP), ikoreshwa mu gutangiza polimeri (urugero: polyvinyl chloride, PVC).
3.2 Isuku n'Isukura mu Nganda
Umuti wo gukuraho amavuta: Ukora neza mu gukuraho amavuta, amavuta, n'ibishashara mu bice by'icyuma (urugero, ibice by'imodoka, imashini) bitewe nuko ifite ubushobozi bukomeye bwo gukaraba hydrocarbon.
Gusiga no Gufata: Bigabanya resins, lacquers, na kole kugira ngo bihindure ubushyuhe, bigatuma bikoreshwa neza kandi bigakira vuba (bikoreshwa mu gusiga imbaho, kole zo mu nganda).
3.3 Imikoreshereze ya Laboratwari n'Isesengura
Chromatography Solvent: Ikoreshwa nk'igice cy'itsinda rigendanwa muri chromatography ya gaz (GC) na chromatography y'amazi ifite imikorere myiza (HPLC) mu gutandukanya isesengura ry'ibinyabuzima.
Umushongi wo gutegura icyitegererezo: Ushongesha ingero zikomeye (urugero, lipide, polymere) kugira ngo zisesengurwe mu buryo bwa shimi (urugero, Fourier-transform infrared spectroscopy, FTIR).
3.4 Ibikomoka kuri peteroli n'ingufu
Inyongeramusaruro: Ivanze na lisansi kugira ngo yongere ubushobozi bwa octane kandi igabanye gukubita kwa moteri; kandi yongera ubushobozi bwo kugumana lisansi mu gihe cyo kubika.
Umutekano no kubahiriza amategeko
4.1 Amabwiriza y'umutekano
Ingaruka zo gushya: Amazi n'umwuka bishobora gushya cyane; wirinde inkongi z'umuriro, ibishashi, n'ubushyuhe (koresha ibikoresho bidashobora guturika mu duce dukoreshwamo).
Ikorwa rya Peroxide: Ishobora gukora peroxide iturika iyo ihuye n’umwuka, urumuri, cyangwa ubushyuhe uko igihe kigenda gihita. Gerageza peroxide (ukoresheje impapuro za starch-iyode) mbere yo kuyikoresha; jugunya iyo peroxide ibonetse.
Ibikoresho byo Kwirinda: Ambara uturindantoki twa nitrile, indorerwamo za shimi, n'icyuma gihumeka umwuka (N95 cyangwa irenga) ahantu hadafite umwuka mwiza. Irinde ko uruhu/amaso bitera umujinya no guhumeka umwuka (bishobora gutera isesemi cyangwa isesemi).
Kubika: Bika ahantu hakonje, hijimye, kandi hari umwuka mwiza; koresha ibikombe by'ikirahure cy'umuhondo cyangwa HDPE bidahumeka. Shyiramo umuti ubuza peroxide (urugero: hydroquinone) kugira ngo bibikwe igihe kirekire.
4.2 Iyubahirizwa ry'amategeko
REACH (EU): Yanditswe muri REACH (Nomero yo kwiyandikisha: 01-2119488787-46-xxxx); yubahiriza amabwiriza ku myanda ya peroxide.
OSHA (Amerika): Umupaka w'ibiza ku kazi (OEL): 500 ppm (TWA y'amasaha 8); ishyirwa mu cyiciro cy'amazi ashobora gushya (NFPA Class IB).
Ibyiciro bya GHS: GHS02 (Amazi ashobora gushya), GHS07 (Iritera), GHS08 (Ishobora gukora peroxide iturika).
Amabwiriza ya ISO: Yujuje ibisabwa na ISO 6353-2 (Ibipimo by'urwego rwa Reagent) kugira ngo bikoreshwe muri laboratwari.
Incamake y'amakuru ya tekiniki (TDS)

| Ibisigazwa bidahinduka (ntarengwa) | 5 mg/kg | 1 mg/kg | Gravimetri |
Kuki twahitamo Isopropyl Ether yacu (CAS 108-20-3)?
Ingaruka nke za Peroxide: Igicuruzwa cyacu gihamye hamwe n’ibipimo byo kwirinda ibiryo, bigabanya ikorwa rya peroxide kandi bigafasha mu kwirinda ikoreshwa ry’ibiyobyabwenge.
Ubuziranenge Buhoraho: Kugenzura ubuziranenge bw’ibice bitandukanye (≥99.0% ku rwego rw’inganda) bigabanya imyanda ibangamira imikorere.
Gupakira byihariye: Biboneka mu mato ya 1L, 20L, 200L, cyangwa mu bigega bya ISO ku bicuruzwa bito bya 实验室 cyangwa mu nganda nini.
Ubufasha mu bya tekiniki: Ikipe yacu itanga ubuyobozi ku igeragezwa rya peroxide, ububiko, no kunoza ikoreshwa ryayo (urugero, kuvanga ibinyabutabire kugira ngo bivangwe).
Iyubahirizwa ry’amategeko mpuzamahanga: Yujuje ibisabwa ku rwego mpuzamahanga (REACH, OSHA, ISO) kugira ngo ikoreshwe ku masoko y’ibihugu by’Uburayi, Amerika na Aziya.
