Nā Waiwai Kemika

He wai ʻā ʻole, moakāka a melemele māmā paha. He ʻala ʻawaʻawa ikaika. Hiki ke hui pū ʻia me ka ethanol (decomposition), diethylene glycol, ether, acetone, carbon tetrachloride, benzene, chlorobenzene, kerosene, a me ka ʻaila ʻoliva.

Hoʻohana:

Hoʻohana ʻia ma ke ʻano he mea maka no ka hana ʻana i ka polyurethane flexible foam, coatings, rubber a me nā adhesives

ʻAno hana

1. Hoʻomākaukau ʻia e ka hopena o 2,4-diaminotoluene a me phosgene. ʻO ka mea mua, e hoʻoheheʻe i ka diaminotoluene paʻa i loko o ka benzene chlorinated, a hoʻomehana iā ia i 70°C me ka hoʻoulu ʻana e loaʻa ai kahi hopena diaminotoluene chlorobenzene. Hoʻokomo ʻia ka phosgenated benzene oxide i hoʻihoʻi ʻia i loko o kahi ipu phosgene haʻahaʻa a hoʻohui ʻia kekahi nui o ka mālamalama wai. Ma hope o ka gasification, e hoʻohui i ka hopena diaminotoluene i hoʻomākaukau ʻia i kulu ʻia me ka hoʻoulu ʻana i ka Chemicalbook, e hana i ka phosgenation ma 40°C, a laila e hoʻokomo i ka mea phosgenation haʻahaʻa i loko o kahi ipu wela kiʻekiʻe no ka phosgenation wela kiʻekiʻe, a ea i ka wā e hoʻomehana ana, no kahi o 4 mau hola, hana pinepine ʻia ka hopena ma 120 ~ 125℃; ma hope o ka pau ʻana o ka hopena, loaʻa ia ma ka hoʻomaʻemaʻe ʻana me ka nitrogen, distilling, a me ka hoʻoponopono ʻana.
