Isopropyl Ether obedo gin ma lyel, ma lyel ma ki ngeyo pi kit ma en tiyo kwede me juku jami. Ma calo gin ma ki lwongo ni mid-polarity solvent, en rwate ki jami ma kwo ki ma nok, ma miyo en bedo gin ma pire tek i yubu jami ma ki lwongo ni chemical synthesis, kwanyo, ki lwoko i gang tic. Kabedo ne ma lapiny ki kit ma en twero loko kwede bene weko bedo yot me nongo ne i yub me distillation, ma konyo wel cente ma mite ki gwoko ne.

Isopropyl Ether's solvent versatility and volatility miyo en bedo gin ma pire tek i kin tic mapol:
3.1 Yub me jami ma ki lwongo ni Chemical Synthesis & Kwany
Kit ma ki yubu kwede jami ma kwo: tiyo calo gin ma ki lwongo ni reaction solvent pi Grignard reactions, alkylations, ki esterifications. Polarity ne ma lapiny konyo me juku rwom me tic ki medo rwom me jami ma ki yubu pi non-polar intermediates.
Kwanyo ki pii: Ki tiyo kwede me poko jami ma kwo ki pii (me labolle, kwanyo jami ma ki tiyo kwede me cango two, yat ma neko kwidi, onyo jami ma miyo mit ki i pii ma ki yubu ki pii onyo jami ma ki kwanyo ki i kom yadi).
Yub me Peroxide: Tiiyo calo gin ma ki tiyo kwede me yubu diisopropyl perooxydicarbonate (IPP), gin ma ki tiyo kwede me cako yubu polymer (me labolle, polyvinyl chloride, PVC).
3.2 Yub me lwoko ki keto bongo i kom dano
Gin ma kwanyo moo: tiyo maber me kwanyo moo, moo, ki moo ki i kom jami ma ki yubu ki nyonyo (me labolle, jami ma ki tiyo kwede i motoka, jami ma ki tiyo kwede) pien en twero juku jami ma ki lwongo ni hydrocarbons.
Coating & Adhesive Formulations: Dilutes resins, lacquers, ki adhesives me loko rwom me ngwec, neno ni tic maber ki dongo oyotoyot (ki tiyo kwede i wood coatings, industrial adhesives).
3.3 Tic ki Laboratory & Analytical Tices
Chromatography Solvent: Ki tiyo kwede ma calo gin ma ki lwongo ni mobile phase component i gas chromatography (GC) ki high-performance liquid chromatography (HPLC) me poko jami ma kwo.
Gin ma ki tiyo kwede me yubu gin ma ki nyutu: kwanyo gin ma ki nyutu (me labolle, moo, jami ma ki lwongo ni polymers) pi nyamo jami (me labolle, Fourier-transform infrared spectroscopy, FTIR).
3.4 Moo ki teko
Gin ma ki medo i moo: ki rubu ki moo me medo rwom me octane ki dwoko piny goro pa injin; bene medo rwom me moo i kare me gwoko ne.
Gwok ki lubu cik
4.1 Cik me gwoko kwo
Peko me lyel: Pii ki yamo ma lyel matek; gwok ki mac ma lyel, mac ma lyel, ki jami ma lyel (tic ki jami ma gengo wang i kabedo ma itye ka tic kwede).
Yub pa Peroxide: Twero yubu peroxide ma twero wango ka ki keto i yamo, lero, onyo lyeto pi kare malac. Tem pi peroxides (kun itiyo ki karatac ma ki lwongo ni starch-iodide) ma peya itiyo kwede; bolo woko ka kinongo ni tye ki peroxides.
Tic ki jami me gwoke: Ruk cing ma ki yubu ki nitrile, bongo ma ki keto i kom dano, ki gin ma ki lwongo ni vapor respirator (N95 onyo ma malo) i kabedo ma yamo pe donyo iye maber. Kur rwate ki del kom/wang (twero kelo arem) ki yweyo yamo (twero kelo wic nyo arem ic).
Ka gwoko: Gwok kama piny ngiic, macol, ma yamo donyo iye maber; tii ki jami ma yamo pe donyo iye, ma ki yubu ki gilaci macol onyo HDPE. Med gin ma gengo peroxide (me labolle, hydroquinone) pi gwoko ne pi kare malac.
4.2 Lubu cik
REACH (EU): Ki coyo piny i REACH (Namba me coyo nying: 01-2119488787-46-xxxx); ma lubu cik ma kwako jami ma ki lwongo ni peroxide.
OSHA (US): Occupational Exposure Limit (OEL): 500 ppm (8-hour TWA); ki poko calo gin ma lyel (NFPA Class IB).
GHS Kit ma ki poko kwede: GHS02 (Pii ma lyel), GHS07 (Gin ma kelo lworo), GHS08 (Twero yubu jami ma wango mac).
ISO Standards: rwate ki ISO 6353-2 (Reagent grade specifications) pi tic kwede i ot yat.
Karatac me ngec ma mako tic (TDS) ma pire tek

| Non - Volatile Residue (max) | 5 mg/kg | 1 mg/kg | Gravimetry |
Pingo wa yero gin ma ki lwongo ni Isopropyl Ether (CAS 108-20-3)?
Peko me Peroxide ma lapiny: Jami ma wa yubu ni ki gwoko ki jami ma gengo cam, ma dwoko piny peroxide ki neno ni tic kwede maber.
Lengo ma rwate: Gwoko lengo pa dul acel acel (≥99.0% pi rwom me tic) dwoko piny jami ma balo tic.
Kit ma ki yubu kwede: Tye i 1L, 20L, 200L drums, onyo ISO tanks pi jami ma nok 实验室 onyo jami mapol.
Kony me tic: Dul wa miiyo pwony i kom temo peroxide, gwoko ne, ki tic kwede maber (me labolle, rubu gin ma ki lwongo ni solvent me kwanyo).
Lubu cik me wilobo: rwate ki rwom me wilobo (REACH, OSHA, ISO) me tic kwede i cuk me EU, US, ki Asia.
