Intangiriro

Acide Aminobenzene sulfonique, izwi kandi nka sulfamine phenol, ni ifumbire mvaruganda. Ibikurikira ni intangiriro kumiterere, imikoreshereze, uburyo bwo gutegura namakuru yumutekano ya p-aminobenzene sulfonic aside:

 

Ubwiza:

Acide Aminobenzenesulfonic ni ifu yera ya kristaline itagira impumuro nziza kandi igashonga mumazi na Ethanol.

 

Imikoreshereze: Irashobora kandi gukoreshwa muguhuza amarangi amwe hamwe nibikoresho bya shimi.

 

Uburyo:

Acide Aminobenzenesulfonic irashobora kuboneka bitewe na reaction ya benzenesulfonyl chloride na aniline. Ubwa mbere, aniline na alkali byegeranye kugirango bibe aside m-aminobenzene sulfonique, hanyuma aside aminobenzene sulfonique ibonwa na acylation reaction.

 

Amakuru yumutekano:

Usibye ingaruka zabyo zibabaza amaso, uruhu, n'inzira z'ubuhumekero, aside aminobenzene sulfonic ntabwo yigeze ivugwa ko ari uburozi cyangwa akaga. Mugihe ukoresheje cyangwa ukoresha aside aminobenzene sulfonique, komeza guhumeka neza, irinde guhura namaso nuruhu, kandi wambare ibikoresho birinda nibiba ngombwa. Niba byatewe n'impanuka cyangwa byakozweho, hita witabaza muganga. Mugihe cyo kubika no kubika, bigomba kubikwa ahantu humye, hakonje, kure yumuriro nibindi bintu byaka.
