I-Ethyl Acetoacetate (EAA)

I-Ethyl acetoacetate (EAA) iyi-β-keto ester yakudala futhi ingeyodwa yamabhulokhi wokwakha aguquguquka kakhulu ekuhlanganiseni kwezinto eziphilayo. Ngenxa yeqembu layo le-methylene elisebenzayo elizungezwe imisebenzi emibili ye-carbonyl, i-EAA ibhekana kalula nokufihlwa kwe-Knoevenagel, izengezo zikaMichael, nokusabela kwe-acylation, okuyenza ibaluleke kakhulu ekuhlanganiseni kwemithi, ukuhlanganiswa kwe-agrochemical, kanye nokwakheka kwe-flavour & iphunga.

Izicelo Ezibalulekile ze-Ethyl Acetoacetate (EAA)

Pharmaceutical Intermediates

Okubalulekile kokuqala kokuhlanganiswa kwama-API

Amakhemikhali ezolimo

Isetshenziswa ekukhiqizeni ama-herbicides esimanje, ama-fungicides, nama-insecticides (isb., i-pyrazole ne-triazole derivatives)

I-Flavour & Fragrance

Inikeza amanothi anezithelo, afana ne-rum, ne-cognac; Isimo se-GRAS lapho sikhiqizwa ngaphansi kwezimo zebanga lokudla

Amadayi nezingulube

Isandulela samadayi e-azo kanye ne-heterocyclic pigment intermediates

I-Solvent & Specialty Chemicals

I-solvent ebilayo kakhulu, enobuthi obuncane yezingubo namayinki

Imibuzo Evame Ukubuzwa (FAQs)

Q: Uyini umehluko phakathi kwe-Ethyl Acetoacetate ne-Methyl Acetoacetate?

A: I-Ethyl acetoacetate (EAA) ineqembu le-ethyl ester, kuyilapho i-methyl acetoacetate (MAA) ine-methyl ester. I-EAA isetshenziswa kakhulu ezimbonini ngenxa yezindleko eziphansi kanye nokuphatha kalula. I-MAA kwesinye isikhathi iyakhethwa ekuphenduleni okudinga ukwenziwa kabusha okuphakeme noma imikhiqizo ephansi ebilisayo.

Umbuzo: Kungani i-EAA inuka isithelo?

A: Isici esimnandi, esiphundu, sephunga elifana ne-rum livela ku-enol tautomer yayo futhi ilandelela ukungcola okuguquguqukayo okwakhiwa ngesikhathi sokulondoloza.

Umbuzo: Ingabe i-methyl pyruvate izinzile ekamelweni lokushisa?

A: Iyazinza uma igcinwe ku-2–8 °C esitsheni esivaliwe esivikelwe ekukhanyeni. Emazingeni okushisa asekamelweni ibola kancane kancane noma ipholise, ikakhulukazi uma ichayeke kumswakama noma emoyeni.

Umbuzo: Ngingakwazi ukusebenzisa i-methyl pyruvate ekudleni noma ekwenziweni kwezimonyo?

A: I-Methyl pyruvate i-FEMA GRAS (No. 2673) njengento yokwenziwa yesinongo uma isetshenziswa ngaphakathi kwemikhawulo ye-FDA (21 CFR 172.515). Ngokusetshenziswa kwezimonyo, qinisekisa ukuthobela imithetho yesifunda (isb., I-EU Cosmetics Regulation, China IECIC).

Q: Yiziphi izincibilikisi i-methyl pyruvate exubana nazo?

A: Ixubene ngokugcwele ne-ethanol, i-acetone, i-diethyl ether, i-dichloromethane, kanye nezinyibilikisi eziningi eziphilayo. Ukuncibilika okulinganiselwe emanzini.

Ngingayithenga kuphi i-Ethyl Acetoacetate (EAA) yekhwalithi ephezulu?
