Nadiifinta sareeysa ee Methyl acetoacetate Reagent 99%

Gaar ahaan: 220kg / durbaan

Methyl acetoacetate, oo loo soo gaabiyo MAA oo si nidaamsan loogu magac daray methyl 3-oxobutanoate, waa dareere huruud ah oo aan midab lahayn oo cirro leh oo leh ur miro leh oo sifada beta-keto esters. Badeecadeena tayada sare leh waxay gaartaa 99% nadiif ah, oo keenaysa waxqabad la isku halayn karo oo loogu talagalay isku-dhafka dawooyinka, wax-soo-saarka beeraha, wax-soo-saarka midabka, iyo isbeddellada dabiiciga ah ee horumarsan.

Sida beta-keto ester-ka ugu fudud, methyl acetoacetate waxay leedahay falcelin kiimiko oo gaar ah oo ka dhalatay joogitaanka labada koox ee ketone iyo ester-ka oo ay kala soocaan hal unug methylene. Qaab dhismeedkan 1,3-dicarbonyl wuxuu awood u siinayaa dariiqooyin falcelineed oo kala duwan oo ay ku jiraan samaynta enolate, falcelinta uumiga, iyo beddelka nucleophilic ee goobo badan. Xaruntu waxay inta badan ku jirtaa qaabka keto (qiyaastii 92%) oo leh enol tautomer yar (8%), taasoo bixisa falcelin la taaban karo oo loogu talagalay codsiyada synthetic.

Warshadaha dawooyinka ayaa ka dhigan qayb codsi oo weyn, halkaas oo methyl acetoacetate ay u adeegto sidii dhisme muhiim ah oo loogu talagalay isku-darka xeryahooda heterocyclic, gaar ahaan pyrazoles, pyrimidines, iyo pyridones oo leh firfircoonida dawooyinka. Xaruntu waxay ka qaybqaadataa isku-darka Knorr pyrazole, falcelinta Biginelli, iyo uumiga ka kooban qaybo badan oo si hufan u dhisa unugyo isku dhafan oo isku dhafan oo loogu talagalay helitaanka iyo horumarinta daroogada.

Wax soo saarka beeraha, MAA waxay u shaqeysaa sidii dhexdhexaadka soo saarista fungicides, herbicides, iyo nidaamiyayaasha koritaanka dhirta. Warshadaha midabaynta iyo dheeha waxa ay uga faa'idaystaan ​​soo saarista midabka jaalaha ah ee azo pigment iyo isku xidhka qaybaha midabeeyayaasha. Codsiyada dheeraadka ah waxaa ka mid ah isticmaalka sida dareere loogu talagalay soosaarayaasha cellulose, qayb ka mid ah kiimikooyinka sawir-qaadista, iyo walxaha bilawga ah ee soo saarista polymers-ka acetoacetate-ka iyo resins.

99% saafiga ah ee methyl acetoacetate waxay la kulmeysaa tilmaamo adag oo loogu talagalay saamiga keto-enol joogto ah, aysidhka hooseeya, iyo kakoobnaanta qoyaanka ugu yar, hubinta natiijooyinka falcelinta la isku halayn karo ee soosaarayaasha dawooyinka, soosaarayaasha agrochemical, iyo soosaarayaasha kiimikada gaarka ah ee u baahan shaqada heerka sare ee beta-keto ester si loo dalbado codsiyada synthetic.

Shirkaddayadu waxay si qoto dheer ugu hawlan tahay warshadaha kiimikada waxayna inta badan wax ka qabataa noocyo kala duwan oo alaabta ceeriin kiimikaad ah sida surfactants, kiimikooyinka ganaaxa ee saliidda, alaabta ceeriin ee aasaasiga ah, dareerayaasha organic, dhexdhexaadinta dawooyinka iyo sunta cayayaanka, wakiilada daaweynta biyaha, iyo cuntada lagu daro. Alaabooyinkeeda ayaa si weyn looga isticmaalaa warshado kala duwan.

Kiimikadayada sida aadka ah loo iibiyo waxaa ka mid ah dareerayaasha warshadaha iyo dhexdhexaadiyeyaasha kiimikaad, sida Taxanaha Alcohol, Taxanaha Ether, Esters, Precursor Series, Acid-Ester Solvents, Bacrimiyeyaasha NPK-Biyaha-Milan, iyo Kiimikada kale ee Warshadaha. Alaabooyinkani waxay ka kooban yihiin sahay deggan, nadiifnimo la isku halayn karo, iyo heerar tayo leh oo joogto ah. Weydiinta waa la soo dhawaynayaa.
