2.4 Dimethylaniline (C8H11N), maopopo iā ʻoe?

No hea mai ia a no ke aha ia?

He wai ʻaila kala ʻole. Hoʻonui ke kala i ka mālamalama a me ka ea. Hiki ke hoʻoheheʻe ʻia i loko o ka wai, hiki ke hoʻoheheʻe ʻia i ka ethanol, ether, benzene a me nā ʻakika.

I ka manawa like, ua hoʻokaʻawale ʻia mai ka m-xylene e loaʻa ai ka 2,4-dimethylnitrobenzene a me 2,6-dimethylnitrobenzene. Ma hope o ka hoʻoponopono ʻana, hoʻohui ʻia ka 2,4-dimethylnitrobenzene i ka catalytically. Nā huahana i loaʻa ma ka hoʻemi hydrogen.

ʻO nā mea ʻawaʻawa, hiki ke puhi ʻia i ke ahi ākea; hoʻopili me nā mea oxidants; decomposes toxic nitrogen oxide uahi me ka wela nui. I ka wā o ka mālama ʻana a me ka lawe ʻana, pono e hoʻoheheʻe ʻia ka hale kūʻai a maloʻo i ka haʻahaʻa haʻahaʻa; e mālama kaʻawale mai nā waikawa, oxidants, a me nā mea hoʻohui meaʻai.
