3. Ua haujlwm zoo li cov khoom siv tshuaj zoo, txhim khu kev qha tshwj xeeb polymers nrog thermal stability zoo heev rau kev siv txheej txheej txheej.
Cia thiab ceev faj
Khaws Phenylpropiolic acid CAS 637-44-5 nyob rau hauv kaw HDPE / amber iav nruas ntawm 5-25℃nyob rau hauv ib tug txias, qhuav, zoo-ventilated cheeb tsam, deb ntawm qhib hluav taws, muaj zog oxidants, muaj zog bases thiab txo cov neeg ua hauj. Hnav hnab looj tes nitrile, looj tsom iav dub thiab plua plav npog; tsis txhob nqus plua plav, tawv nqaij / qhov muag thiab kev noj, uas yuav ua rau mob me me rau cov mucous membranes. Reseal nruj nreem tom qab siv; neutralize pov tseg nrog dilute alkali ua ntej pov tseg, nruj me ntsis txwv tsis pub tso dej ncaj qha thiab sib xyaw nrog cov khoom sib xyaw.
Dab tsi yog qhov txiaj ntsig ntawm kev noj Phenylpropiolic acid?
Phenylpropiolic acid CAS 637-44-5 is a low-toxic alkynyl aromatic acid (oral LD50>2000mg / kg), tsuas yog me me corrosive irritation ntawm kev sib cuag ncaj qha; tsis muaj qhov tshwm sim tshwm sim raws li qhov qub cia.
Hauv kev tswj hwm kev siv, Phenylpropiolic acid CAS 637-44-5 nta siab reactivity ntawm triple daim ntawv cog lus / carboxyl pawg rau ntau yam organic synthesis, zoo solubility nyob rau hauv ethanol / acetone / ethyl acetate, zoo heev thermal stability thaum lub sij hawm ua, thiab cov phenylalkynyl qauv txhim kho molecular rigidity, purification thiab purity siab.
