I-Dicyclohexylamine

Ukusetyenziswa

I-Dicyclohexylamine isetyenziswa kakhulu kwicandelo le-accelerators zerabha eyenziweyo, i-metal corrosion inhibitors, i-surfactants, iikhemikhali ze-oyile, amayeza kunye nezibulali-zinambuzane. Ngokuhambela phambili kwesayensi netekhnoloji, usetyenziso lwayo olutsha luhlala luphuhliswa, kwaye iikhemikhali ezintle eziye zenziwa ngempumelelo ziimveliso ezintsha ezinamathuba ophuhliso.

ukulungiselela

I-hydrorefining reactor yi-tubular fixed-bed reactor enobubanzi obungaphakathi obuyi-20 mm. I-catalyst yi-nickel-based high-activity catalyst enomthamo omiselweyo we-15 mL. I-catalyst ifakwe kwindawo ye-isothermal ye-reactor. Ubungakanani be-particle yi-20 mesh ukuya kwi-40 mesh. Umlinganiselo wobunzima bento nganye yesinyithi kwi-catalyst yi: Ni:Al:Mo=85:5:5. I-crude dicyclohexylamine kunye ne-hydrogen zingeniswa ukusuka kwinxalenye ephezulu ye-reactor ukuze zenze i-hydrorefining reaction. Iimveliso ziqokelelwa rhoqo kwaye zihlalutywe ukusuka kwisiphelo esisezantsi se-reactor. I-hydrogen emva kokwahlulwa kwegesi nolwelo iyafunyanwa kwaye isetyenziswe kwakhona. Ulwakhiwo (ipesenti yobunzima) lwe-dicyclohexylamine eluhlaza kwiChemicalbook yi-10.15% cyclohexylamine, 5.11% aniline, 79.91% dicyclohexylamine, 0.31% dicyclohexyleneamine, 0.1% cyclohexylaniline, kunye ne-1.88% cyclohexeneaniline. %. Iimeko zokusabela: 180°C, 3.5MPa, isantya sesithuba somthamo wolwelo yi-0.2h-1, umlinganiselo we-hydrogen ukuya kwioyile yi-1000. Ukusasazwa kwemveliso emva kokucoca nge-hydro: cyclohexylamine 5.76%, aniline 0%, dicyclohexylamine 93.03%, dicyclohexyleneamine 0%, cyclohexylaniline 0.01%, cyclohexeneaniline 0%.

Iipropati zeKhemikhali

Ulwelo olunamafutha olungenambala nolucacileyo olunevumba elibi le-ammonia. Lunyibilika kancinci emanzini, luxutywa nezinyibilikisi zendalo.

Indlela yokuvelisa:

Ukusebenzisa i-aniline njengezinto eziluhlaza, i-hydrogenation kubushushu obuphezulu kunye noxinzelelo oluphezulu xa kukho i-catalyst isetyenziselwa ukulungisa i-dicyclohexylamine.
