Hoʻolauna

ʻO Methyl 2, he mea hoʻohuihui mea ola me ke kumu kemika C7H4Cl2NO2. Eia ka wehewehe ʻana o nā waiwai, hoʻohana, hoʻomākaukau a me ka ʻike palekana o ka pūhui:

 

ʻAno:

- methyl 2, he wai kala ʻole.

-He ʻala ʻala ʻono kona.

- Hiki ke hoʻoheheʻe ʻia ka hui i loko o kahi mea hoʻoheheʻe kūlohelohe e like me ka methanol a i ʻole dichloromethane.

-ʻO kona helu hoʻoheheʻe ma kahi o 43-47 ° C, a ʻo kona wahi hoʻolapalapa ma kahi o 257-263 ° C.

 

E hoʻohana:

- methyl 2, hoʻohana mau ʻia ma ke ʻano he kikowaena synthetic no nā pesticides a me nā insecticides.

-Hiki ke hoʻohana ʻia e synthesize i nā pūhui ʻē aʻe i loko o ka kemika synthetic synthetic.

 

Kaʻina hoʻomākaukau:

- methyl 2, hiki ke hoʻomākaukau ʻia e nā pae aʻe:

1. ʻO ka mua, ua esterified ka waikawa 2,5-dichloronicotinic me ka waika formic.

2. Hoʻokō pinepine ʻia ka hopena ma lalo o nā kūlana ʻawaʻawa, a hoʻohui ʻia kahi mea hoʻoheheʻe, e like me ka waiʻona a i ʻole ka mea hoʻoheheʻe waika, e hoʻoikaika i ka hopena.

3. Ma hope o ka pau ʻana o ka hopena, hoʻokaʻawale ʻia ka huahana i hoʻopaʻa ʻia a hoʻomaʻemaʻe ʻia mai ka hui ʻana ma o ka distillation a i ʻole ka unuhi ʻana.

 

ʻIke palekana:

- methyl 2, he mea hoʻonāukiuki i hiki ke loaʻa ka hopena hoʻonāukiuki i nā maka, ka ʻili a me nā membrane mucous.

-E hoʻohana i nā lako pale pilikino kūpono e like me nā aniani, nā mīkina lima a me nā lole pale i ka wā e lawelawe ai a hoʻohana.

-Pono ia mai ke ahi a me ka wela wela e pale ai i ka pilikia o ke ahi a me ka pahū.

-I ka mālama ʻana a me ka mālama ʻana, e hahai pono i nā kaʻina hana palekana e pale i ka hui ʻana a me ka hoʻopili ʻana me nā mea ʻē aʻe.

-Inā hoʻokomo ʻia a inhaled paha, e ʻimi koke i ka lāʻau lapaʻau a hāʻawi i kahi pepa ʻikepili palekana a i ʻole ka lepili no ka kemika.
