Grayish chena kusvika tsvuku kristaro kana pulp. Sodium m-aminobenzene sulfonate yakawanikwa ne sulfonation reaction ye nitrobenzene uye kuderedza. Inoshandiswa kugadzira azo dhayi uye mishonga yepakati, reactive, acidic, sulfide uye mamwe madhayi.
METANIC ACIDSODIUM MUNYU
英文 名 词: m-aminobenzenesulfonic ACID SODIUM SALT; SODIUM METANILATE.
CAS kwete. : 1126-34-7
EINECS Nhamba : 214-419-3 [1]
Molecular formula: C6H6NNaO3S
Molecular uremu: 195.1734
Chitarisiko: Grayish chena kune chiedza tsvuku crystal kana slurry
Kirasi yakachena yakanaka. Iyo tembiricha yekuora yekristaro inowanikwa kubva mumvura ndeye 302 ~ 304 ℃.
Metanilic acidine greyish chena kuti chiedza tsvuku chitarisiko sekristaro kana slurry
Total amino content, % ≥60
Zvemukati, % ≥90
Zviri mukati mezvinhu zvisinganyungudika musoda, % ≤1.5
Zvishandiso: inoshandiswa mukugadzira azo dhayi uye mishonga yepakati, reactive, acid, sulfide uye mamwe madhayi.
Nzira yekugadzira nzira: iyo sulfonation reaction ye nitrobenzene uye fuming sulfuric acid inoitwa pa115 ℃, uye chigadzirwa chemaitiro chinodzorwa kuti chisarerekera nealkali yemvura, uye ipapo iyo sodium solution ye m-nitrobenzene sulfonate inosefa. Mushonga wacho wakaderedzwa nesimbi shavings secatalyst yekuwana m-aminobenzene sulfonate, uye dhaka resimbi rakabviswa nekusefa. Iyo filtrate yaive m-aminobenzene sulfonate munyu. Wedzera sulfuric acid mupoto yekubvisa asidhi kusvika bepa reCongo dzvuku rekuyedza rashanduka bhuruu, uye chengetedza tembiricha iri pa70℃. Zvadaro, iyo m-aminobenzene sulfonate slurry inowanikwa ne centrifugation filtration.
Toxicity uye kudzivirira: chigadzirwa ichi chine muchetura zvakanyanya. Kumedza kana kunwa mukati meganda kunogona kukonzera chepfu yakakomba. Nekudaro, huturu hwayo hwakanyanya kuderera pane aniline, uye haizokonzeri carcinogenic mhedzisiro. Munguva yekugadzira, inofanirwa kudzivirirwa zvakanyanya kubva pakupfeka netsaona kana kupuruzira ganda, michina yekugadzira inofanirwa kuvharwa kudzivirira kuvuza, uye anoshanda anofanira kupfeka zvekudzivirira.
Kurongedza uye kuchengetedza: chengetedza munzvimbo inotonhorera, ine mhepo uye yakaoma, kudzivirira kupisa, mwando uye zuva. Chengetedza uye kutakura zvinoenderana nemirairo yezvechepfu.
