Dicyclohexylamine

Kagwiritsidwe Ntchito

Dicyclohexylamine imagwiritsidwa ntchito kwambiri m'magawo a zothamangitsa mphira zopangidwa, zoletsa dzimbiri zachitsulo, zoyambitsa ma surfactants, mankhwala am'munda wamafuta, mankhwala ndi mankhwala ophera tizilombo. Ndi kupita patsogolo kwa sayansi ndi ukadaulo, ntchito zake zatsopano zikupangidwa nthawi zonse, ndipo mankhwala abwino omwe apangidwa bwino makamaka ndi zinthu zatsopano zomwe zikuyembekezeka kupangidwa.

kukonzekera

Choyatsira madzi ndi choyatsira cha tubular chokhazikika chokhala ndi mainchesi 20 mkati. Choyatsira madzi ndi choyatsira champhamvu chokhala ndi nickel chokhala ndi voliyumu yokhazikika ya 15 mL. Choyatsira chimayikidwa mu gawo la isothermal la choyatsira. Kukula kwa tinthu tating'onoting'ono ndi 20 mesh mpaka 40 mesh. Chiŵerengero cha kulemera kwa chinthu chilichonse chachitsulo mu choyatsira ndi: Ni:Al:Mo=85:5:5. Dicyclohexylamine yopanda kanthu ndi haidrojeni zimalowetsedwa kuchokera kumtunda kwa choyatsira madzi kuti zichite hydrorefining reaction. Zogulitsazo zimasonkhanitsidwa ndikusanthulidwa mosalekeza kuchokera kumapeto kwa choyatsira. Haidrojeni pambuyo pa kulekanitsidwa kwa gasi ndi madzi imabwezeretsedwanso ndikugwiritsidwanso ntchito. Kapangidwe (kulemera kwa chiŵerengero) cha dicyclohexylamine yosaphikidwa mu Chemicalbook ndi 10.15% cyclohexylamine, 5.11% aniline, 79.91% dicyclohexylamine, 0.31% dicyclohexyleneamine, 0.1% cyclohexylaniline, ndi 1.88% cyclohexeneaniline. %. Mikhalidwe ya reaction: 180°C, 3.5MPa, liquid voliyumu space velocity 0.2h-1, hydrogen to oil ratio 1000. Kugawa kwa mankhwala pambuyo pa hydrorefining: cyclohexylamine 5.76%, aniline 0%, dicyclohexylamine 93.03%, dicyclohexyleneamine 0%, cyclohexylaniline 0.01%, cyclohexeneaniline 0%.

Katundu wa Mankhwala

Madzi amafuta opanda mtundu komanso owonekera bwino okhala ndi fungo la amoniya. Amasungunuka pang'ono m'madzi, amatha kusakanikirana ndi zinthu zachilengedwe.

Njira yopangira:

Pogwiritsa ntchito aniline ngati zopangira, hydrogenation pa kutentha kwakukulu ndi kuthamanga kwambiri pamaso pa chothandizira imagwiritsidwa ntchito pokonzekera dicyclohexylamine.
