Isopropyl Ether nchintu chikonzya kupya, chipya chizibinkene akaambo kakukonzya kwacho kusungwaazya. Mbuli chintu chili akati-akati, chibamba kabotu zintu zipona azintu zitakwe nguzu, akupa kuti ube chintu chipati mukupanga misamu, kugwisya, akusalazya mumafakitali. Ikupya kwawo kusyoonto akuzungaana kwawo aakati-akati akwalo kupa kuti kube kujokolosya kuuba-uba munzila zyakusanzya, kugwasya kubelesya mali manji akuzumanana.
Zintu zipati abubotu
| Lubono | Kusalazya | Bubotu bupati |
| Kunywika | Kunywika mbichaani mumaanzi (~1.2 g/L a 20°C); ilakonzya kusanganyigwa a ethanol, acetone, benzene, azintu zyiingi zipangwa azintu zipona | Zilakonzya kubelesegwa munzila zyiingi zyakunyonyoona mafuta, ma resini, ma wax, antoomwe azintu zipona; kweendelana azintu zibelesyegwa antoomwe |
| Kuchincha | Kuyuma kwamuwo: 16.9 kPa a 20°C; busena bwakubila buniini (68 - 69°C) | Zipa kuti kufwambaane kuvwuuma muchiindi chakuvwumba/kuyuminizya; kwaandaanya kuuba kwiinda mukusanzya |
| Kukkalilila kwamakemikalu | Chikkalilila mubukkale bwakuyobweda buli kabotu; ilabola asyoonto-asyoonto kuti yaswaangana ama asidi mayumu naa ma peroxide | Chisyomeka mukubamba kwachiindi chilamfu (kuti chikwabilidwe kuzwa kuma peroxides); kuchita zintu ziniini azintu zyiingi |
| Bupati (20°C) | 0.725 g/cm3 | Bunji bwabantu buche bucheya mali yakweenzya; nchuubauba kubelesya mukusanganya maanzi |
| Kupya Kwakuliyaka | 443°C (829°F) | Kukwabililwa kwiinda zintu zipya kapati (nkokuti, diethyl ether) mumasena aatakweendelezyegwi |
Kubelesya kwachiindi choonse
Isopropyl Ether's solvent vertility and volatility kupa kuti ibe chintu chiyandikana mumakkampani miingi:
3.1 Kupanga akugwisya misamu
Kupanga zintu zipona: Kubeleka mbuli chintu chipa kuti kube kusanduka kwa Grignard, alkylations, antoomwe a esterifications. Kubula nguzu kwayo kusyoonto kulagwasya kweendelezya mweelwe wakusanduka akusumpula mpindu zyazintu zitali zyaakati-kati.
Kugwisya Maanzi: Kubelesyegwa kwaandaanya zintu zipona kuzwa kuzintu zili mumaanzi (nkokuti, kugwisya misamu, misamu iijaya tuzunda, naa zintu zipa kuti muntu afwe nsoni kuzwa kuzintu zipangwa azisyango).
Kupanga Peroxide: Kubeleka mbuli chintu chibelesegwa mukupanga diisopropyl peroxidicarbonate (IPP), chintu chidumide chakutalisya kupanga polymer (nkokuti, polyvinyl chloride, PVC).
3.2 Kusalazya akuvwumba mumafakitali
Musamu wakugwisya mafuta: Ulagwasya kugwisya mafuta, mafuta, a wax kuzwa kuzibeela zyabutale (nkokuti, zibeela zyamyootokala, minchina) akaambo kakuti ulakonzya kugwisya mafuta aa hydrocarbons.
Zibelesyo zyakuvwumba azyakunamatika: Zipa kuti ma resini, ma lacquer, azintu zyakunamatika zibe kabotu, kuchitila kuti zibelesyegwe kabotu akufwambaana kuyuma (zibelesyegwa mukuvwumba zisamu, zintu zyakunamatika zyamafakitali).
3.3 Kubelesya kwa laboratory akuvwuntauzya
Chromatography Solvent: Ibelesyegwa mbuli chintu chikonzya kweenda mu gas chromatography (GC) antoomwe a high-performance liquid chromatography (HPLC) kwaandaanya zintu zipona.
Chibelesyo chakubamba zitondezyo: Chisanzya zitondezyo ziyumu (nkokuti, mafuta, ma polymer) kuti zibelesyegwe mukuvwuntauzya (nkokuti, Fourier-transform infrared spectroscopy, FTIR).
3.4 Mafuta anguzu
Chiyungizyo chamafuta: chakasanganyigwa amafuta kuti chiyungizye mweelwe wa octane akucesya kugonka kwa injini; alimwi chisumpula kukkalikana kwamafuta muchiindi chakuyobola.
Lukwabililo akutobela milawu
4.1 Malailile aakukwabilila
Ntenda Yakupya: Maanzi alimwi amuwo uupya kapati; kkala kule amulilo uuvwilima, mulilo, azintu zipya (belesya zibelesyo zitakonzyi kupwasuka mumasena aakubelesya).
Kupangwa kwa Peroxide: Kulakonzya kupanga ma peroxide aakonzya kupwasuka aawo nabikkwa mumuwo, mumuni, naa kupya kwachiindi chilamfu. Amusunke ma peroxide (kubelesya pepa lya starch-iodide) kamutanabelesya; sowa kuti kwajanika ma peroxides.
Kujata Zibelesyo Zyakukwabilila: Kosama magilovu aa nitrile, magilazi aakubelesya misamu iikola, antoomwe achibelesyo chakuyoya (N95 naa kwiinda waawo) mumasena aatakwe muya mubotu. Kozyiba kujata chikumba/meso (kulakonzya kuleta kunyema) akuyoya busi (kulakonzya kuleta kuzungaana naa kuzwa bulo).
Kubamba: Kobamba mubusena butontola, busiya, bujisi muuya mubotu; kobelesya zintu zitanjili muya, gilazi lya amber naa HDPE. Koyungizya chintu chilesya kuzwa mumubili (nkokuti, hydroquinone) kuti chibambe kwachiindi chilamfu.
4.2 Kutobelezya milawu
REACH (EU): Yakalembwa a REACH (Namba yakulembesya: 01-2119488787-46-xxxx); kweendelana amilawu iijatikizya tombe lya peroxide.
OSHA (US): Occupational Exposure Limit (OEL): 500 ppm (8-hour TWA); yakabikkwa mubusena bwamaanzi aakonzya kupya (NFPA Class IB).
GHS Classification: GHS02 (Flammable Liquid), GHS07 (Irritant), GHS08 (Ilakonzya kupanga ma peroxides aakonzya kupya).
ISO Standards: Zilazuzikizya ISO 6353-2 (Reagent grade specifications) zyakubelesya mu laboratory.
Pepa lyamakani aabusongo (TDS) Twaambo Tupati
| Paramita | Chiimo chamakwebo | Chiimo cha Reagent | Nzila Yakusunka |
| Kusalala (miniti) | 99.0% | 99.5% | Gas Chromatography (GC) |
| Buteteete (max) | 0.1% | 0.05% | Karl Fischer Titration |

Nkaambo nzi ncotweelede kusala Isopropyl Ether (CAS 108-20-3)?
Ntenda ya Peroxide nsyoonto: Chintu chesu chilikwabilidwe azintu zikonzya kulesya zyakulya, ikucheesya kupanga peroxide akusinizya kuti chibelesyegwe kabotu.
Busalali butazungaani: Kubamba kusalala kuzwa kuli umwi awumwi (≥99.0% yamumakkampani) kulacesya tombe linyonganya nzila zyakuchita zintu.
Kupakila kweendelana amuntu: Kulajanwa mu 1L, 20L, 200L, naa ISO matanki aa 实验室 masyoonto naa maoda manji.
Lugwasyo lwabusongo: Nkamu yesu ilapa busolozi bwakusunka peroxide, kubamba, akubelesya kabotu (nkokuti, kusanganya solvent kuti igwisigwe).
Kutobelezya munyika yoonse: Kuzuzikizya zyeelelo zyanyika yoonse (REACH, OSHA, ISO) zyakubelesya mumisika ya EU, US, antoomwe aya Asia.
