ʻO Dicyclohexylamine

Hoʻohana

Hoʻohana nui ʻia ʻo Dicyclohexylamine ma nā kahua o nā mea hoʻolalelale rubber synthetic, nā mea pale i ka palaho metala, nā surfactants, nā kemika kahua ʻaila, nā lāʻau lapaʻau a me nā pesticides. Me ka holomua o ka ʻepekema a me ka ʻenehana, ke hoʻomohala mau ʻia nei kāna mau noi hou, a ʻo nā kemika maikaʻi i hoʻohui maikaʻi ʻia he mau huahana hou me nā manaʻolana hoʻomohala.

hoʻomākaukau

He reactor moe paʻa tubular ka reactor hydrorefining me ke anawaena o loko o 20 mm. He mea hoʻonui hana kiʻekiʻe i hoʻokumu ʻia i ka nickel me ka nui paʻa o 15 mL ka mea hoʻonui. Hoʻokomo ʻia ka mea hoʻonui ma ka ʻāpana isothermal o ka reactor. ʻO ka nui o ka ʻāpana he 20 mesh i 40 mesh. ʻO ka lakio nui o kēlā me kēia mea metala i loko o ka mea hoʻonui: Ni:Al:Mo=85:5: 5. Hoʻokomo ʻia ka dicyclohexylamine maka a me ka hydrogen mai ka ʻaoʻao o luna o ka reactor e hana i kahi hopena hydrorefining. Hōʻiliʻili mau ʻia nā huahana a kālailai ʻia mai ka ʻaoʻao haʻahaʻa o ka reactor. Hoʻihoʻi ʻia ka hydrogen ma hope o ka hoʻokaʻawale ʻana o ke kinoea-wai a hoʻohana hou ʻia. ʻO ka haku mele (pakeneka kaumaha) o ka dicyclohexylamine maka ma Chemicalbook he 10.15% cyclohexylamine, 5.11% aniline, 79.91% dicyclohexylamine, 0.31% dicyclohexyleneamine, 0.1% cyclohexylaniline, a me 1.88% cyclohexeneaniline. %. Nā kūlana pane: 180°C, 3.5MPa, ka wikiwiki o ka leo wai 0.2h-1, ka lakio hydrogen i ka ʻaila 1000. Ka hoʻolaha huahana ma hope o ka hydrorefining: cyclohexylamine 5.76%, aniline 0%, dicyclohexylamine 93.03%, dicyclohexyleneamine 0%, cyclohexylaniline 0.01%, cyclohexeneaniline 0%.

Nā Waiwai Kemika

He wai ʻaila ʻole kala a moakaka me ke ʻala ʻamonia ʻawaʻawa. Hoʻoheheʻe iki ʻia i ka wai, hiki ke hui pū ʻia me nā mea hoʻoheheʻe organik.

ʻAno hana:

Ke hoʻohana nei i ka aniline ma ke ʻano he mea maka, hoʻohana ʻia ka hydrogenation ma ke ana wela kiʻekiʻe a me ke kaomi kiʻekiʻe i ke alo o kahi mea hoʻoulu e hoʻomākaukau i ka dicyclohexylamine.
