Phthalic Anhydride (PA) CAS No.: 85-44-9

Lus piav qhia luv luv:

Product Overview

Phthalic Anhydride (PA) yog ib qho tseem ceeb ntawm cov organic chemical raw khoom, feem ntau ua los ntawm oxidation ntawm ortho-xylene los yog naphthalene. Nws zoo nkaus li dawb crystalline khoom nrog me ntsis irritating tsw. PA yog dav siv nyob rau hauv zus tau tej cov plasticizers, unsaturated polyester resins, alkyd resins, dyes, thiab pigments, ua rau nws yog ib qho tseem ceeb nruab nrab ntawm cov tshuaj lom neeg kev lag luam.

Ntsiab nta

• Siab Reactivity:PA muaj cov pab pawg anhydride, uas nkag siab zoo nrog cawv, amines, thiab lwm yam sib txuas los tsim esters lossis amides.
• Solubility zoo:Soluble nyob rau hauv dej kub, cawv, ethers, thiab lwm yam organic solvents.
• Kev ruaj ntseg:Nyob ruaj khov nyob rau hauv qhuav tej yam kev mob tab sis hydrolyzes maj mam mus rau phthalic acid nyob rau hauv lub xub ntiag ntawm dej.
• Versatility:Siv nyob rau hauv cov synthesis ntawm ntau yam khoom siv tshuaj, ua rau nws muaj ntau yam.

Daim ntawv thov

1. Plasticizers:Siv los tsim phthalate esters (piv txwv li, DOP, DBP), uas tau siv dav hauv PVC cov khoom los txhim kho kev yooj yim thiab kev ua haujlwm.
2. Unsaturated Polyester Resins:Siv rau hauv kev tsim cov fiberglass, coatings, thiab adhesives, muab cov khoom siv zoo heev thiab tshuaj lom neeg.
3. Alkyd Resins:Siv nyob rau hauv cov xim, coatings, thiab varnishes, muab zoo adhesion thiab gloss.
4. Dyes thiab Pigments:Ua haujlwm li nruab nrab hauv kev sib txuas ntawm anthraquinone dyes thiab pigments.
5. Lwm yam kev siv:Siv rau hauv kev tsim cov tshuaj intermediates, tshuaj tua kab, thiab tshuaj tsw qab.

Ntim & Cia

• Ntim:Muaj nyob rau hauv 25 kg / hnab, 500 kg / hnab, los yog ton hnab. Kev xaiv ntim khoom muaj nyob rau ntawm kev thov.
• Cia:Khaws rau hauv qhov chaw txias, qhuav, thiab qhov cua zoo. Tsis txhob kov cov dej noo. Pom zoo cia kub: 15-25 ℃.

Kev nyab xeeb & kev xav txog ib puag ncig

• Kev khaus khaus:PA ua rau tawv nqaij, qhov muag, thiab ua pa. Cov cuab yeej tiv thaiv zoo (xws li, hnab looj tes, tsom iav, lub tshuab ua pa) yuav tsum tau hnav thaum tuav.
• Flammability:Combustible tab sis tsis heev flammable. Khaws kom deb ntawm qhov qhib nplaim taws thiab qhov kub thiab txias.
• Environmental Impact:Pov tseg cov ntaub ntawv pov tseg raws li cov cai hauv cheeb tsam ib puag ncig kom tsis txhob muaj kuab paug.
