Hoʻolauna

ʻO 2,6-Dinitrotoluene, ka mea i kapa ʻia ʻo DNMT, he mea hoʻohuihui. He paʻa kala kala ʻole ʻaʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai ma ka lumi wela a hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me ka ether a me ka petroleum ether.

 

Hoʻohana nui ʻia ka 2,6-Dinitrotoluene ma ke ʻano he mea hoʻohui i nā mea pahū a me nā mea pahū. Loaʻa iā ia ka hana pahū kiʻekiʻe a me ke kūpaʻa, a hoʻohana pinepine ʻia i ka hoʻomākaukau ʻana i nā mea pahū kīwila a me ka pūʻali koa.

 

ʻO ke ʻano o ka hoʻomākaukau ʻana i ka 2,6-dinitrotoluene e loaʻa pinepine ʻia e ka nitrification o toluene. ʻO ke ʻano hoʻomākaukau kikoʻī e pili ana i ka toluene dropwise i loko o kahi hui o ka waikawa nitric a me ka waikawa sulfuric, a lawe ʻia ka hopena ma lalo o nā kūlana wela.

 

Ma keʻano o ka palekana, 2,6-dinitrotoluene he mea pōʻino. He mea hoʻonāukiuki loa a me ke kino kino, a hiki ke hoʻoulu i ka huhū a me nā hopena maʻi ke hoʻohu ʻia a pili pū paha me ka ʻili. I ka wā e hana ai, pono e mālama ʻia nā hana palekana, e like me ke komo ʻana i nā mīkina lima pale, nā aniani a me nā respirator, a me ka hana ʻana ma kahi wahi i hoʻoluʻu maikaʻi ʻia. ʻO ka mālamaʻana a me ka mālamaʻana i ka 2,6-dinitrotoluene pono e hoʻokō i nā kānāwai a me nā kūlana kūpono e hōʻoia i ka palekana pilikino a me ka palekana o ka nohona.
