Nadiifi-sare Dimethyl Sulfate Reagent 99%

Gaar ahaan: 250kg / durbaan

Dimethyl sulfate, oo loo soo gaabiyo DMS sidoo kalena loo yaqaan sulfuric acid dimethyl ester, waa dareere aan midab lahayn, saliid leh oo daciif ah, ur basasha u eg. Badeecadeena nadiifka ah waxay gaartaa 99% diiradda, bixinta waxtarka methylating gaarka ah ee isku dhafka daawada, wax soo saarka agrochemical, wax soo saarka dheeha, iyo codsiyada khaaska ah ee alkylation warshadaha.

Maaddaama uu yahay wakiilka methylating ee ugu badan ee loo isticmaalo kimistariga warshadaha, dimethyl sulfate wuxuu leeyahay astaamo falcelin gaar ah oo ka sooca deeq-bixiyayaasha methyl kale. Unugyadu waxa ay ka kooban tahay laba kooxood oo methyl aadka u firfircoon oo ku xidhan xudunta dhexe ee sulfate, taas oo awood u siinaysa falcelinta methylation-ka ee xidhiidhsan ee leh dhaqaalaha atamka sare. Awoodda kooxda ee aadka u fiican ee methyl sulfate anion waxay sahlaysaa falcelinta beddelka nucleophilic ee amines, phenols, asiidhyada karboxilic, iyo nucleophiles kale oo ku hoos jira xaalado khafiif ah, oo caadi ahaan soo saara wax soo saar sare oo leh falcelino dhinaca ugu yar.

Warshadaha dawooyinku waxay ka dhigan yihiin qayb codsi oo muhiim ah, halkaas oo DMS ay u adeegto sidii reagen muhiim u ah soo saarista maaddooyinka dawooyinka firfircoon ee methylated. Waxay si wax ku ool ah u methylates nitrogen, oxygen, iyo atamka sulfur ee xeryahooda heterocyclic, taas oo awood u siinaysa isku dhafka antihistamines, anticholinergics, iyo wakiilada daaweynta kala duwan. Darajada nadiifka sare waxay hubisaa dimethyl ether ugu yar iyo wasakhda aashitada taasoo wax u dhimi karta xulashada falcelinta iyo tayada alaabta.

Wax soo saarka agrochemical, dimethyl sulfate wuxuu u shaqeeyaa sidii dhexdhexaadiye muhiim ah oo loogu talagalay soo saarista sunta cayayaanka, herbicides, iyo nidaamiyeyaasha koritaanka dhirta iyada oo loo marayo falcelinta N-methylation iyo O-methylation hufan. Warshadaha dheeha iyo midabaynta waxay u isticmaalaan DMS si ay u soo saaraan midabada cationic, muraayadaha indhaha, iyo midabada u baahan shaqada nitrogen methylated.

Codsiyada dheeraadka ah waxay ka kooban yihiin isticmaalka soo saarista surfactants, ion-exchange resins, iyo kicinta wareejinta wejiga, iyo sidoo kale methylation of cusbada aan organic ee codsiyada gaarka ah. Xaaladda dareeraha ee xarunta ee heerkulka jawigu wuxuu fududeeyaa cabbiraadda saxda ah iyo maaraynta hawlgallada habaynta ee joogtada ah marka la barbar dhigo beddelka methylating gaseous.

Ogeysiiska Badbaadada: Dimethyl sulfate waxaa loo kala saaraa sida kansarka bini'aadamka ee suurtogalka ah iyo sunta awoodda leh oo leh dib-udhac sun ah. Alaabtayadu waxa ku jira dukumeenti badbaado oo dhamaystiran iyo borotokoolka maaraynta. Dhammaan hawlgallada waxay u baahan yihiin kontaroolada injineernimada, qalabka ilaalinta shakhsi ahaaneed, iyo u hoggaansanaanta adag ee xaddidaadda soo-gaadhista shaqada.

99% saafiga ah ee dimethyl sulfate waxay la kulantaa qeexitaanno adag oo loogu talagalay aysidhka hooseeya, nuxurka biyaha ugu yar, iyo heerarka ether-ka ee la kantaroolo, hubinta waxqabadka methylation ee la isku halayn karo ee soosaarayaasha dawooyinka, soosaarayaasha agrochemical, iyo soosaarayaasha kiimikada gaarka ah ee u baahan wakiilka methylating waxtarka sare leh ee dalbanaya hawlgallada isku dhafka warshadaha.

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.
