Dicyclohexylamine

Fa'aaogāga

E fa'aaogā tele le Dicyclohexylamine i vaega o mea fa'avavevave o le pa'u fa'apitoa, mea e taofia ai le 'ele'ele o u'amea, mea e fa'amama ai siama, vaila'au fa'asaina mai le suau'u, vaila'au fa'asaina ma vaila'au fa'asaina. Fa'atasi ai ma le alualu i luma o le saienisi ma tekinolosi, o lo'o fa'aauau pea ona atia'e ona fa'aoga fou, ma o vaila'au lelei ua fa'aputuina ma le manuia o oloa fou ia e iai fa'amoemoega e atiina ae.

sauniuniga

O le reactor hydrorefining o se reactor fixed-bed tubular ma le lautele i totonu e 20 mm. O le catalyst o se catalyst maualuga-gaioiga e faʻavae i le nickel ma se voluma tumau e 15 mL. O loʻo faʻapipiʻiina le catalyst i le isothermal zone o le reactor. O le tele o le particle e 20 mesh i le 40 mesh. O le fua faatatau o le mamafa o elemene uʻamea taʻitasi i totonu o le catalyst o le: Ni:Al:Mo=85:5: 5. O le dicyclohexylamine mata ma le hydrogen e faʻaofi mai le pito i luga o le reactor e faʻatino ai se tali hydrorefining. O oloa e aoina pea ma auʻiliʻili mai le pito i lalo o le reactor. O le hydrogen pe a uma ona vavaeʻeseina le kesi-vai e toe maua mai ma toe faʻaaogaina. O le tuufaatasiga (pasene mamafa) o le dicyclohexylamine mata i le Chemicalbook e 10.15% cyclohexylamine, 5.11% aniline, 79.91% dicyclohexylamine, 0.31% dicyclohexyleneamine, 0.1% cyclohexylaniline, ma le 1.88% cyclohexeneaniline. %. Tulaga o le tali atu: 180°C, 3.5MPa, saoasaoa o le avanoa o le vai 0.2h-1, fua faatatau o le hydrogen i le suauu 1000. Faasalalauga o oloa pe a uma le hydrorefining: cyclohexylamine 5.76%, aniline 0%, dicyclohexylamine 93.03%, dicyclohexyleneamine 0%, cyclohexylaniline 0.01%, cyclohexeneaniline 0%.

Meatotino Fa'akemikolo

O se vai e leai se lanu ma manino ma e manogi malosi le ammonia. E fai si faigofie ona solo i le vai, e mafai ona fefiloi ma vaila'au fa'aola.

Metotia gaosiga:

I le faʻaaogaina o le aniline o se mea mata, o le hydrogenation i le vevela maualuga ma le mamafa maualuga i le i ai o se catalyst e faʻaaogaina e saunia ai le dicyclohexylamine.
