Diethyl Fumarate

Zouping Jinxing Tshuaj Co., Ltd. Yog tias koj yuav mus rau cov lag luam wholesale bulk diethyl fumarate 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.

Cov tsos mob: Tsis muaj xim rau daj daj daj pob tshab kua (siab- qib purity yuav crystallize ntawm qhov kub thiab txias)
Melting point: 1-2℃(qee cov ntaub ntawv hais txog 1.5 degree); kua ntawm chav tsev kub
Kub taw tes: 218-220℃(atmospheric siab); 102-104℃/ 15 mmHg (tso siab)
Ceev: 1.052 g / cm³ (20 degree; denser dua dej)
Refractive index: n²⁰_D 1.441–1.443
Flash point: 92-94℃(kaw khob); combustible kua (tsis cais raws li qis-flash-point)
Solubility: Sparingly soluble hauv dej (kwv yees . 0.5 g / L ntawm 20 degree); miscible nrog ethanol, diethyl ether, acetone, ethyl acetate, thiab aromatic hydrocarbons; muaj peev xwm ntawm dissolving tej acrylics / unsaturated polyesters

Organic synthesis intermediate: Diels{0}}Alder synthesis ntawm cyclic diesters; sab-chain precursor rau kws tshuaj (xws li, pimobendan) thiab agrochemicals.
Unsaturated polyester resin (UPR) monomer: Copolymerized nrog maleic anhydride los yog phthalic anhydride los kho resin yooj thiab reactivity (lub *trans* isomer contributes rau qis cross-link density).
Fragrance/Solvent: Siv nyob rau hauv me me raws li ib tug siab - boiling hnyav los yog cov tshuaj tiv thaiv nruab nrab; possesses tsis tseem ceeb aroma nws tus kheej.
Cov qauv ntsuas: Siv rau GC calibration thiab isomer sib cais siv (paired nrog diethyl maleate).

Mob toxicity: Tsawg toxicity; rat qhov ncauj LD₅₀≈ 3200 mg/kg (piv rau diethyl maleate).
Irritation: Nruab nrab qhov muag / tawv nqaij irritant; GHS H315/H319/H335.
Ntev- teebmeem: Tsis muaj pov thawj tshwj xeeb ntawm teratogenicity lossis carcinogenicity; Txawm li cas los xij, raws li cov ester unsaturated, ntev ntev ntawm daim tawv nqaij yuav tsum raug zam.
Flammability/Explosion: Combustible; tua nrog ua npuas ncauj, hmoov qhuav, CO₂, los yog xuab zeb / ntiaj teb.
Kev Tiv Thaiv: Kov hauv fume hood; hnav looj tsom iav dub thiab hnab looj tes nitrile; tswj raws li combustible, qis -toxicity unsaturated ester.
Cia thiab thauj: Khaws rau hauv lub thawv kaw kom deb ntawm lub teeb (kom tiv thaiv kev yees duab-isomerization lossis polymerization); khaws cais los ntawm cov oxidizers muaj zog thiab muaj zog hauv paus.
