2.4 Dimethylaniline (C8H11N), koj puas paub nws?

Nws los ntawm qhov twg thiab nws siv rau dab tsi?

Nws yog cov kua uas tsis muaj xim oily. Xim tob rau hauv lub teeb thiab huab cua. Me ntsis soluble nyob rau hauv dej, soluble nyob rau hauv ethanol, ether, benzene thiab acid daws. Siv raws li intermediates rau tshuaj tua kab, tshuaj thiab dyes.

Nyob rau tib lub sijhawm, nws yog nitrated los ntawm m-xylene kom tau 2,4-dimethylnitrobenzene thiab 2,6-dimethylnitrobenzene. Tom qab kho, 2,4-dimethylnitrobenzene ntxiv catalytically. Cov khoom tau txais los ntawm kev txo qis hydrogen.

Cov khoom muaj kuab lom, flammable nyob rau hauv qhib nplaim taws; reacts nrog oxidants; decomposes lom nitrogen oxide pa luam yeeb nrog kub kub. Thaum lub sij hawm cia thiab thauj mus los, lub warehouse yuav tsum tau ventilated thiab qhuav ntawm tsawg kub; khaws nws cais los ntawm cov kua qaub, oxidants, thiab zaub mov additives.
