2,5-DimethoxybenzaldehydeCAS 93-02-7ke motsoako oa bohlokoa oa manyolo o nang le ts'ebeliso e latelang, litšobotsi le melemo:

1. Kopo

(1) Bohareng ba meriana:2,5-Dimethoxybenzaldehydee sebelisoa haholo ho motsoako oa lithethefatsi, mohlala, e le setsi sa bohlokoa bakeng sa ho lokisetsa li-antibacterial agents, lithethefatsi tse thibelang likokoana-hloko kapa limolek'hule tse ling tse rarahaneng.
(2) Indasteri ea dae le monko o monate: Lefapheng la dae le monko o monate, 2,5-Dimethoxybenzaldehyde e ka sebelisoa e le lisebelisoa tse tala bakeng sa motsoako oa metsoako e nkhang hamonate, e fanang ka sehlahisoa monko o itseng kapa 'mala.
(3) Likokoana-hloko le li-preservative: Liphuputso tse ling li bontšitse hore 2,5-Dimethoxybenzaldehyde e ka sebelisoa e le selelekela sa li-fungicides kapa li-preservative, haholo-holo ho nts'etsopele ea lihlahisoa tse sireletsang tikoloho.
(4) Patlisiso ea motsoako oa lintho tse phelang: 2,5-Dimethoxybenzaldehyde e atisa ho sebelisoa ha ho etsoa condensation, redox reactions, joalo-joalo ka motsoako oa lintho tse phelang ka lebaka la sehlopha sa eona se sebetsang sa aldehyde le sebopeho sa sebaka sa methoxyl.

2. Litšobotsi

(1) Lintho tsa 'mele le tsa lik'hemik'hale
Sebaka se qhibilihang: 46-48 ° C (hote.), phofo e khanyang ea kristale e mosehla.
Ntho e belang: 283.8 ° C ka khatello e tloaelehileng, 146 ° C ka khatello e tlaase (10 mmHg), e loketseng ho arabela mocheso o phahameng14.
Solubility: Ho qhibiliha ha bonolo ka har'a metsoako ea tlhaho e kang ethanol, ether, chloroform, 'me e qhibiliha hanyenyane metsing.
Boima: hoo e ka bang 1.1 g/cm³, index ea refractive 1.534.

(2) Botsitso le kutlo:
E nyenyefatsa moea, e hloka ho koaloa le ho bolokoa hole le leseli ho thibela oxidation kapa ho bola.
Thepa ea lik'hemik'hale e tsitsitse, empa e ka 'na ea arabela boteng ba li-oxidants tse matla.

(3) Litšobotsi tsa polokeho:
Kotsi: Hoa teneha (GHS07/GHS08). Ho ama letlalo kapa mahlo ho ka baka ho teneha, 'me ho hema ho ka baka ho hana ho phefumoloha.
Litlhoko tsa polokelo: E hloka ho bolokoa sebakeng se pholileng le se omileng 'me u qobe ho kopana le li-oxidants tse matla.

3. Melemo

(1) Reactivity e phahameng: Tšusumetso ea synergistic ea aldehyde le lihlopha tsa methoxy e etsa hore e sebetse hantle haholo ho organic synthesis, haholo-holo e loketseng ho haha ​​mehaho e rarahaneng ea limolek'hule.
(2) Ho feto-fetoha ha maemo:2,5-Dimethoxybenzaldehydee ka sebelisoa e le sesebelisoa sa ho qala bakeng sa karabelo e fapaneng, joalo ka condensation, alkylation, joalo-joalo, mme mefuta ea eona ea ts'ebeliso e akaretsa likarolo tse ngata joalo ka meriana le lisebelisoa.
(3) Tlhahiso ea indasteri e hōlileng tsebong: Ts'ebetso ea tlhahiso ea 2,5-Dimethoxybenzaldehyde e batla e hōlile. Re ka fana ka litlhaloso tse fapaneng (tse kang 99% bohloeki) le ho paka (25kg / barrel, 500g / mokotla, joalo-joalo) ho finyella litlhoko tsa laboratori le indasteri.
(4) Matla a ho sireletsa tikoloho: Liphuputso li bontšitse seo2,5-Dimethoxybenzaldehydee ka sebelisoa hape ka ho ntšoa ha litšila (joalo ka lignin derivatives), e tsamaellanang le mokhoa oa nts'etsopele oa k'hemistri e tala.
