Kugira ngo amazi y’imyanda agabanure no kwongera igipimo c’uguhindura ibintu, ibigo vy’ubushakashatsi mu gihugu n’ibigo vy’ubuhinga bwa none vyakoresheje ubuhinga bwo mu gihugu kugira ngo bimenyekane, vyatumye habaho uburyo bwo kwihutisha umunyu M, kandi bwashitse ku ngaruka. abashakashatsi b’ivy’ubuhinga bwa none barateguye uburyo bwo gukuraho ibintu nk’ubwo n’ibihugu vyo hanze, ariko kandi hari ingorane. uburyo bwo gukingira ibidukikije, umutekano n’uguhitamwo neza ibintu bishasha vy’ibinyabuzima ni co kintu nyamukuru co gusukura M biciye mu buryo bw’ibinyobwa. uburyo burimwo uburyo bwo guhindura ibara ry’ibintu, uburyo bwo gukuraho amazi, uburyo bwo gukura amazi mu mazi bukomeye, uburyo bwo gukura amazi n’amazi n’ibindi kuri . Ariko rero, ubuhinga ntibutunganye bihagije .
Muri iki gihe, ibintu biva mu bimera birashobora guhitamwo toluene, disulfide, anzene, benzene n’ibindi kuri .
Gukoresha ugusenyuka kw’umuyagankuba nk’ikintu co guhindura, kugenzura ibiciro n’ugucungera umutekano ni ingorane zikomeye.
Iyo aniline ikoreshejwe nk’ikintu co gusukura, aniline irashobora gusenyuka gatoyi mu mazi, ivyo bikaba bituma umubare w’ivyuma vy’umubiri vyiyongera mu mazi, ivyo bikaba bidashoboka mu guhingura .
Benzene na toluene zikoreshwa nk’ibintu bihumanya, ubushobozi bwo gusenyuka kw’iresini ni buto, ubusuku bw’igicuruzwa M burashikirwa, kandi gusubirana kw’ibintu vy’umunyu na vyo nyene bifatwa nk’ivyo . Ikindi, benzene na toluene birashobora guturika, ikintu co gukingira ni gito, kandi uguhinduka kw’ibintu biva ku guhomba kw’umuyaga mu kirere. Ibidukikije vy'ikirere{2}}
