4. Muab 3 4-Difluorobenzoic acid CAS 455-86-7 siab purity thiab zoo ib yam reactivity, haum rau ob qho tib si kuaj-scale R&D thiab loj-scale industrial manufacturing.
Cov ntaub ntawv kev nyab xeeb
3 4-Difluorobenzoic acid CAS 455-86-7 raug cais raws li kev ua xua (H315, H319, H335), ua rau tawv nqaij khaus, khaus qhov muag hnyav thiab ua pa ua pa thaum sib cuag lossis nqus pa. Nws yog incompatible nrog muaj zog bases, amines thiab oxidants; Kev sib xyaw tsis raug yuav ua rau muaj kev puas tsuaj thiab tso tawm cov pa hluav taws xob hydrogen fluoride. Cov khoom siv tuaj yeem tsim cov plua plav thaum tuav, ua rau muaj kev phom sij ntau ntxiv; Kev kis tau ntev ntev tuaj yeem ua rau cov nqaij mos hauv zos o lossis mob me me. Nws tsis raug cais raws li cov khoom siv hluav taws xob, tab sis cov cua kub kub tuaj yeem tsim cov khoom puas tsuaj xws li fluorinated hydrocarbons.
