N-methylaniline ndicho chigadzirwa chikuru muN-alkyl inonhuhwirira amine yakatevedzana uye yakakosha yepakati mumakemikari akanaka. Zvakasiyana-siyana. seti yekutanga yenyika yangu yezvigadzirwa zvekugadzira yakavakwa nerubatsiro rweyaimbova Soviet Union muma1950s. Zvigadzirwa zvinonyanya kushandiswa kugadzira zvinoputika centralizers uye zvinowanzo shandiswa kusanganisa yakatwasuka-run Chemicalbook peturu. Sezvo peturu yakatwasuka ine n-alkanes yakawanda uye yakaderera octane nhamba, inowanzoshandiswa mu Naizvozvo, mamwe ma technician anoshandisa yakatwasuka-run peturu semafuta ekutanga e peturu yakasanganiswa, uye kuwedzera octane nhamba nekuwedzera N-methylaniline kuti ibudirire. zvinangwa zvekutsvaga mari shoma uye kushanda kwepamusoro.

Zvenyama nemakemikari zvivakwa:

N-methylaniline imvura isina ruvara ine mafuta pakamuri tembiricha. Soluble mu ethanol, ether, uye chloroform, isinganyungudike mumvura, isingarasikike nyore nekubuda mumhepo, asi isingakodzeri kugovera mumasilinda einjini dzakawanda-cylinder. Iyo yakagadzikana muzvisikwa uye haina kuora nyore nyore mumhepo uye munzvimbo dzakasviba. Hunhu hukuru hwepeturu yakasanganiswa ine N-methylaniline antiknock agent kunhuwa, kuwanda kwepamusoro, kusagadzika chingamu isina kugezwa, kukosha kweolefin yakaderera, uye kudiwa kweanobatsira antiknock agent akadai seMTBE neMMT.

Application

N-methylaniline chinhu chakanaka chemakemikari chigadzirwa chine huwandu hwakawanda hwekushandisa. Inonyanya kushandiswa kugadzira mishonga yezvipembenene, dhayi, dhayi yepakati, rubber additives uye zvinoputika stabilizers. Inogona zvakare kushandiswa seyakanyungudutsa uye acid inogamuchirwa yeorganic synthesis. Chemicalbook intermediates, acid absorbers uye solvents. Muindasitiri yedhayi, inoshandiswa mukugadzira cationic brilliant red FG, cationic pink B, reactive yellow-brown KGR, nezvimwewo. Inogonawo kushandiswa kuwedzera octane nhamba yepeturu uye organic synthesis, uye inogona kushandiswa zvakare. sechinhu chinonyungudutsa.

Properties:

Mvura inobvira isina ruvara kusvika kutsvuku ine mafuta. Soluble mu ethanol, ether, chloroform, inonyungudika zvishoma mumvura. Isa gradient yero.
