Intangiriro

Methylphenyl ether (izwi nka methylphenyl ether) ni ifumbire mvaruganda. Ibikurikira nintangiriro kumiterere, imikoreshereze, uburyo bwo gutegura namakuru yumutekano ya p-tolusether:

 

Ubwiza:

Methylanisole ni amazi atagira ibara afite impumuro idasanzwe. Ikomatanyirizo rihagaze neza mu kirere kandi ntirishobora gutwikwa nta guhura na okiside ikomeye.

 

Koresha:

Methylanisole ikoreshwa cyane nkumusemburo nganda mu nganda. Irashonga ibintu byinshi kama kandi ikoreshwa muburyo bwo gutwikira, gusukura, kole, amarangi n'impumuro nziza. Irakoreshwa kandi nkigisubizo giciriritse cyangwa igisubizo muri bimwe bya synthesis synthesis.

 

Uburyo:

Methylanises muri rusange itegurwa na etherification ya benzene, kandi intambwe yihariye ni iyo gufata benzene na methanol imbere ya catisale ya aside (nka aside hydrochloric, aside sulfurike) kugirango itange methylanisole. Mubisubizo, catisale ya acide ifasha kwihutisha reaction no gutanga umusaruro mwinshi.

 

Amakuru yumutekano:

Tolusole muri rusange ifite umutekano mugihe gikoreshwa bisanzwe, ariko ibikurikira bigomba kwitonderwa:

1. Iyo ikoreshwa, ibidukikije bihumeka neza bigomba kubungabungwa kugirango birinde kwirundanya kwumwuka wacyo mukirere.

3. Mugihe cyo kubika no gutunganya, hagomba kwirindwa guhura na okiside ikomeye hamwe n’umuriro kugira ngo wirinde impanuka n’umuriro.

4. Uruvange rushobora kurekura imyuka yubumara iyo ibora, bisaba kujugunya neza imyanda nuwashonga.

5.Mu gihe cyo gukoresha no gukoresha methyl anisole, birakenewe gukora mu buryo bwimbitse hashingiwe ku bikorwa bijyanye n’umutekano bireba kugira ngo umutekano w’umubiri w’ibidukikije urusheho kuba mwiza.
