izindaba

2,5-Dimethoxybenzaldehyde(Inombolo ye-CAS: 93-02-7) iyinhlanganisela ebalulekile yezinto eziphilayo. Ngenxa yesakhiwo sayo samakhemikhali esiyingqayizivele nokuguquguquka, ithatha isikhundla esibalulekile emkhakheni wezokwelapha kanye nemboni yamakhemikhali. Ukuhlanzeka kwayo okuphezulu nokusebenza kabusha kuyizinzuzo zayo eziyinhloko, kodwa kufanele kuqashelwe ukuvikela ukuphepha ngesikhathi sokusebenza. Ucwaningo lwesikhathi esizayo mayelana nokuhlanganisa okuluhlaza kanye nokusetshenziswa kwensiza lungase lukhulise izimo zalo zohlelo.

2,5-DimethoxybenzaldehydeI-CAS 93-02-7iyinhlanganisela ebalulekile ye-organic enokusetshenziswa okulandelayo, izici kanye nezinzuzo:

1. Isicelo

(1) Abaphakathi kwezemithi:2,5-Dimethoxybenzaldehydeisetshenziswa kakhulu ekuhlanganiseni kwezidakamizwa, isibonelo, njengesihluthulelo esimaphakathi sokulungiswa kwama-antibacterial agents, izidakamizwa ezilwa namagciwane noma amanye ama-molecule ayinkimbinkimbi.
(2) Imboni yodayi nephunga: Emkhakheni wodayi namakha, i-2,5-Dimethoxybenzaldehyde ingasetshenziswa njengempahla eluhlaza yokuhlanganiswa kwezinhlanganisela ezinuka kamnandi, inikeze umkhiqizo iphunga elithile noma umbala.
(3) Isikhunta nesivimbeli: Okunye ukuhlola kuye kwabonisa ukuthi i-2,5-Dimethoxybenzaldehyde ingase isetshenziswe njengesandulela semithi yokubulala isikhunta noma izivimbelakuvunda, ikakhulukazi ekuthuthukisweni kwemikhiqizo evikela imvelo.
(4) Ucwaningo lwe-organic synthesis: I-2,5-Dimethoxybenzaldehyde ivame ukusetshenziswa ekuphenduleni kwe-condensation, ukusabela kwe-redox, njll. ku-organic synthesis ngenxa yeqembu layo le-aldehyde elisebenzayo kanye nesakhiwo sokushintsha i-methoxyl.

2. Izimpawu

(1) Izakhiwo zomzimba namakhemikhali
Iphuzu elincibilikayo: 46-48°C (okhanyayo), i-crystalline powder ekhanyayo ephuzi.
Iphuzu elibilayo: 283.8°C ngomfutho ojwayelekile, 146°C ngomfutho ophansi (10 mmHg), ofanele ukusabela okuphezulu kwezinga lokushisa14.
Ukunyibilika: kuncibilika kalula kuzincibilikisi eziphilayo njenge-ethanol, i-ether, i-chloroform, futhi inyibilika kancane emanzini.
Ukuminyana: cishe ngu-1.1 g/cm³, inkomba ye-refractive 1.534.

(2) Ukuzinza nokuzwela:
Izwela emoyeni, idinga ukuvalwa futhi igcinwe kude nokukhanya ukuvimbela i-oxidation noma ukubola.
Izakhiwo zamakhemikhali zizinzile, kodwa zingasabela lapho kukhona ama-oxidants aqinile.

(3) Izici zokuphepha:
Ingozi: Iyacasula (GHS07/GHS08). Ukuthinta isikhumba noma amehlo kungase kubangele ukucasuka, futhi ukuhogela kungase kubangele ukungezwani nokuphefumula.
Izidingo zesitoreji: Idinga ukugcinwa endaweni epholile neyomile futhi igweme ukuthintana nama-oxidants aqinile.

3. Izinzuzo

(1) Ukusebenza kabusha okuphezulu: Umphumela we-synergistic we-aldehyde kanye namaqembu e-methoxy uwenza asebenze kahle kakhulu ekuhlanganiseni kwezinto eziphilayo, afaneleke ikakhulukazi ukwakha izakhiwo zamangqamuzana eziyinkimbinkimbi.
(2) Ukuhlukahluka:2,5-Dimethoxybenzaldehydeingasetshenziswa njengesiqalo sokusabela okuhlukahlukene, okufana ne-condensation, i-alkylation, njll., futhi uhla lwayo lokusebenza luhlanganisa izinkambu eziningi ezifana nemithi nezinto zokwakha.
(3) Ukukhiqizwa kwezimboni ezivuthiwe: Inqubo yokukhiqiza ye-2,5-Dimethoxybenzaldehyde isivuthiwe uma kuqhathaniswa. Singahlinzeka ngokucaciswa okuhlukile (okufana nokuhlanzeka okungu-99%) kanye nokupakisha (25kg/umphongolo, 500g/isikhwama, njll.) ukuze sihlangabezane nezidingo zaselabhorethri nezezimboni.
(4) Amandla okuvikela imvelo: Ucwaningo luye lwabonisa lokho2,5-Dimethoxybenzaldehydeingaphinda isetshenziswe ngokukhipha imfucuza (okufana nokuphuma kokuphuma kwe-lignin), okuhambisana nenkambiso yentuthuko yekhemistri eluhlaza.
