Hoʻolauna

ʻO ka methylphenyl ether (ʻike ʻia ʻo methylphenyl ether) he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o p-tolusether:

 

ʻAno maikaʻi:

He wai waihoʻoluʻu ʻole ka Methylanisole me kahi ʻala ʻala. Paʻa paʻa ka pūhui i ka ea a ʻaʻole hiki ke puhi ʻia me ka ʻole o ka hoʻopili ʻana me nā oxidants ikaika.

 

E hoʻohana:

Hoʻohana nui ʻia ʻo Methylanisole ma ke ʻano he solvent organik i ka ʻoihana. Hoʻoheheʻe ʻo ia i nā mea olaola he nui a hoʻohana mau ʻia i nā uhi, nā mea hoʻomaʻemaʻe, nā glues, nā pena a me nā mea ʻala wai. Hoʻohana ʻia ʻo ia ma ke ʻano he mea hoʻoheheʻe a i ʻole ka mea hoʻoheheʻe i kekahi mau mea hoʻoheheʻe synthesis.

 

Hanana:

Hoʻomākaukau maʻamau ʻia nā Methylanises e ka hopena etherification o benzene, a ʻo nā ʻanuʻu kikoʻī e hana i ka benzene a me ka methanol i mua o nā mea hoʻoheheʻe waika (e like me ka waika hydrochloric, sulfuric acid) e hana i ka methylanisole. I ka hopena, kōkua ka mea hoʻoheheʻe waikawa i ka wikiwiki o ka hopena a hana i kahi huahana kiʻekiʻe.

 

ʻIke palekana:

ʻOi aku ka palekana o nā Tolusoles ma lalo o nā kūlana hoʻohana maʻamau, akā pono e hoʻomaopopo ʻia kēia mau mea:

1. I ka wā e hoʻohana ʻia ai, pono e mālama ʻia kahi wahi e hoʻoheheʻe maikaʻi ʻia e pale i ka hōʻiliʻili ʻana o kāna mahu i ka lewa.

3. I ka mālama ʻana a me ka mālama ʻana, pono e pale ʻia ka launa pū ʻana me nā oxidants ikaika a me nā mea puhi ahi i mea e pale ai i nā pōʻino ahi a pahū.

4. Hiki i ka hui ke hoʻokuʻu i nā kinoea ʻawaʻawa i ka wā e pohō ai, e koi ana i ka hoʻolei pono ʻana i nā ʻōpala a me nā mea hoʻoheheʻe.

5. I ke kaʻina hana o ka hoʻohana ʻana a me ka lawelawe ʻana i ka methyl anisole, pono ia e hana ma ke ʻano koʻikoʻi me nā kikoʻī hana palekana kūpono e hōʻoia i ka palekana o ke kino kanaka a me ke kaiapuni.
