trans-2-Hexen-1-Al Diethyl Acetal(CAS#54306-00-2) zivisa
pfuma chaiyo
Chitarisiko: Iyo inowanzoita senge isina ruvara kune yero inopenya inopenya mvura, izvo zvinoita kuti zvive nyore kushanda mumagadzirirwo emakemikari akadai sekutakura zvinhu uye kusanganisa maitiro.
Kunhuwa: Iine kunhuhwirira kwakasarudzika kwemuchero, kutsva uye kwakasikwa. Ichi chimiro chakakwezva kutarisisa kwakawanda mumunda wekunhuhwirira essence, uye chinogona kushandiswa sekiyi mbishi zvinhu zvekusanganisa fruity flavour.
Solubility: Inogona kunyungudika zvakanaka mune zvakawanda organic solvents, senge ethanol, ether, acetone, nezvimwewo, zvichiita kuti zvive nyore kusanganisa uye kuonana nemamwe mareactants mune organic synthesis reaction system; Kunyungudika mumvura kunenge kushoma, izvo zvinoenderana nemutemo wekunyunguduka kweorganic compounds ine yakakwira kabhoni.
Boiling point: Iyo ine yakananga yekubikira nhanho, inova hwaro hwakakosha hwekuparadzanisa uye kucheneswa mashandiro senge distillation uye kugadzirisa. Iyo yekubikira poindi yemasampuli ane akasiyana ekuchenesa anogona kusiyana zvishoma, uye kunaka uye kuchena kwechigadzirwa kunogona kutanga kuongororwa nekuyera nemazvo nzvimbo yekuvira.
4, Chemical properties
Acetal hydrolysis reaction: Pasi pemamiriro ezvinhu ane acidic, iyo diethylacetal chimiro mumorekuru inowanzoitika kune hydrolysis, ichigadzira aldehyde mapoka uye ethanol zvakare. Hunhu uhu hunowanzo shandiswa mune organic synthesis yekushanda kweboka rekushandura kana aldehyde kudzivirira boka, uye inoburitswa panguva yakakodzera kutora chikamu mune zvinotevera maitiro.
Double bond addition reaction: Carbon carbon double bonds inogona kuita senzvimbo dzinoshanda uye kupinda maactions ekuwedzera nehydrogen, halogens, nezvimwewo. Nekudzora mamiriro ekuita uye reagent dosage, nhevedzano yezvakatorwa zvinogona kugadzirwa zvakasarudzwa, zvichipfumisa kusiyana kwemakomboni.
Oxidation reaction: Pasi pekuita kweakakodzera oxidants, mamorekuru anogona kupinda oxidation, kaviri bond breakage, kana imwe oxidation yemapoka ealdehyde kuti abudise anowirirana oxidation zvigadzirwa, zvichipa nzira yekubatanidzwa kwemamwe macompounds akaomarara.
5, Synthesis nzira
Iyo yakajairika yekugadzira nzira ndeyekutanga ne trans-2-hexenal uye kuita nayo neanhydrous ethanol pamberi pe acidic catalysts seyakaoma hydrogen chloride gasi, p-toluenesulfonic acid, nezvimwewo. huwandu hwekushisa kwakadzika kusvika kune tembiricha yekamuri, kudzivirira maitiro eparutivi kubva kuitika; Panguva imwecheteyo, zvinodikanwa kuve nechokwadi chekuti anhydrous nharaunda, sezvo kuvepo kwemvura kunogona kudzosera maitiro ealdol uye kukanganisa goho. Mushure mekuita kwapera, iyo catalyst inowanzogadziriswa nealkaline solution, yozopatsanurwa nedistillation, kugadzirisa uye dzimwe nzira dzekuwana yakakwirira-kuchena yakananga zvigadzirwa.
