Hoʻolauna

ʻO 2,6-Dimethoxyphenol, i kapa ʻia ʻo p-methoxy-m-cresol, he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o 2,6-dimethoxyphenol:

 

Pono: He paʻa keʻokeʻo keʻokeʻo me ka ʻono ʻala ʻala. Aneane hiki ʻole ke hoʻoheheʻe ʻia i loko o ka wai ma ka lumi wela akā hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe e like me ka ethanol a me ka methylene chloride.

 

E hoʻohana:

 

Hanana:

Hiki ke hoʻokō ʻia ke ʻano hoʻomākaukau o 2,6-dimethoxyphenol e ka methyl etherification o p-cresol. ʻO ke kikoʻī, hiki ke hoʻopili ʻia ka p-cresol me ka methanol a me ka wela a me ka refluxed me ka hoʻohana ʻana i kahi catalyst acidic (e laʻa, sulfuric acid) e hana i 2,6-dimethoxyphenol.

 

ʻIke palekana:

Pono e pale ʻia ka ʻike ʻana i ka 2,6-dimethoxyphenol e like me ka hiki. He hopena hoʻonāukiuki paha ia ma ka maka, ka ʻili, a me ka ʻōnaehana hanu. Pono e hoʻohana ʻia nā lako pale pilikino e like me nā mīkina lima a me nā maka aniani i ka wā e hoʻohana ai a lawelawe ʻia paha.
