Hoʻolauna

ʻO ka 3-Methyl-2,4-dichlorobenzoic acid he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, ʻano hoʻomākaukau a me ka ʻike palekana:

 

ʻAno maikaʻi:

- Ke ʻano: paʻa kalakala kala ʻole

- Solubility: hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe kūlohelohe e like me ka ethanol, ether a me ka methylene chloride, hiki ʻole ke hoʻoheheʻe ʻia i ka wai.

 

E hoʻohana:

- Pesticides: 3-methyl-2,4-dichlorobenzoic acid he herbicide ākea ākea e hiki ke hoʻohana ʻia no ka mālama ʻana i ka ulu ʻana o nā mauʻu like ʻole, e like me ka mauʻu a puni nā mea kanu e like me kale, legumes, a me ke kulina.

 

Hanana:

Hiki ke hoʻomākaukau ʻia ka 3-Methyl-2,4-dichlorobenzoic acid e ka chlorination o ka p-methylanise ether (3-methylanisole). Hiki i ke ʻano hoʻomākaukau kikoʻī ke komo i kēia mau ʻanuʻu:

E hoʻopau i ka 3-methylanisole i loko o ka waika hydrochloric anhydrous.

Hoʻohui ʻia ʻo Sodium chlorite (NaClO) a i ʻole potassium chlorite (KClO) ma ke ʻano he kumu chlorine.

Hoʻoulu ʻia ka hui ʻana i nā mahana haʻahaʻa, maʻamau ma waena o 0-5 °C.

Ma hope o ka pau ʻana o ka hopena, kānana ʻia ka hui ʻana a i ʻole e kiʻi ʻia e loaʻa kahi huahana 3-methyl-2,4-dichlorobenzoic acid.

 

ʻIke palekana:

- Hiki i ka 3-Methyl-2,4-dichlorobenzoic acid ke hoʻopilikia i ke kaiapuni, a pono e uku ʻia i ka mālama ʻana i ka hoʻohana ʻana a me ka hoʻolei ʻana i ka ʻōpala.

- Hiki ke hoʻonāukiuki i ka ʻili, ka maka, a me ka ʻōpū o ka hoʻopili pololei ʻana me ka mea, a pono e pale ʻia ka hoʻopili pololei ʻana.

- E hoʻohana i nā mea pale kūpono e like me nā mīkina lima, nā maka aniani, a me nā maka ke hoʻohana ʻia.

- Pono e mālama i ka hui ʻana me nā mea kemika ʻē aʻe i ka wā o ka mālama ʻana a me ka mālama ʻana, a pale aku i ka ʻā a me nā wela kiʻekiʻe.

- E ʻoluʻolu e heluhelu a hahai i nā pepa ʻikepili palekana kūpono a me nā kuhikuhi hana ma mua o ka hoʻohana ʻana.
