Isopropyl Acetate

Zouping Jinxing Chemical Co., Ltd. yog ib qho ntawm cov ua lag luam thiab cov muag khoom ntawm isopropyl acetate hauv Suav teb. Yog tias koj yuav mus rau cov lag luam wholesale bulk isopropyl acetate hauv Suav teb, txais tos kom tau txais cov qauv dawb los ntawm peb lub hoobkas. Tag nrho cov khoom customized yog nrog cov khoom zoo thiab tus nqi qis.

Melting point: -73.4 ° C
Boiling point: 88.4–89.0℃(qhov siab ntawm huab cua; approx. 12.5℃qis dua *n*-propyl acetate; siab dua ethyl acetate tab sis qis dua butyl acetate)
Qhov ceev: 0.871-0.874 g / cm³ (20 degree; lighter dua dej)
Flash point: 2℃(kaw khob)-flammable heev, Class I flammable kua (tseem ceeb ntau txaus ntshai tshaj *n*-propyl acetate ntawm 14 degree; piv rau ethyl acetate)
Refractive index: n²⁰_D 1.377
Vapor siab: kwv yees . 6.3 kPa (20 degree)

Cov khoom siv dav dav ntawm esters: Acid/base-catalyzed hydrolysis yields acetic acid thiab isopropanol; Txij li thaum lub boiling point ntawm isopropanol (82.5 degree) yog ze rau ntawm cov ester, kev sib cais ntawm rectification yuav tsum tau azeotropic distillation los yog extraction.
Stability: ruaj khov ntawm chav tsev kub; khaws cia rau hauv ib lub thawv ntim, noo noo- pov thawj; hydrolysis yog ceev los ntawm muaj zog acids los yog hauv paus ntawm qhov kub thiab txias.
Tsis hnov ​​​​mob nrog cov hlau lossis roj hmab, tab sis ua rau o ntawm qee cov elastomers uas tsis hnyav- tiv taus.

Nruab nrab-cov kuab tshuaj kom qhuav sai: Siv rau hauv cov coatings, ntoo tiav, automotive refinish xim, thiab inks los kho leveling thiab ziab tus nqi (qis dua EA, sai dua n-propyl acetate).
Nitrocellulose (NC) lacquers: Ib qho hnyav hnyav rau NC cov tsho loj; tiv thaiv blushing.
Extraction agent: Siv rau extracting tshuaj tsw qab thiab tshuaj tua kab mob (penicillins) thiab rau cov nroj tsuag tseem ceeb roj extraction.
Electronics/precision tu: Ib qho ceev- ziab degreaser hloov acetone los yog IPA (evaporates sai dua IPA thiab muaj zog solvency).
Organic synthesis: Siv los tsim isopropyl cawv derivatives thiab fragrance precursors.

Mob toxicity: Tsawg toxicity; Qhov ncauj LD₅₀ hauv nas ≈ 3800 mg/kg; high vapor concentrations ua rau cov tshuaj loog thiab khaus rau qhov muag thiab qhov ntswg.
Irritation: mob qhov muag nruab nrab; ua rau tawv nqaij defatting thiab dryness.
Flammability/Explosion: Explosive txwv 1.8%–7.8% (v/v); vapor hnyav dua li huab cua.
Kev tiv thaiv: tawg- pov thawj qhov cua, cov pa roj carbon monoxide, hnab looj tes nitrile; UN 1220, Class 3, PG II.
Cia / Thauj: Nitrogen blanketing rau tag nrho cov tso tsheb hlau luam; kom deb ntawm alkalis, muaj zog acids, thiab oxidizing tus neeg sawv cev.
