3-METHYL-5-ISOXAZOLEACETIC ACID (CAS#19668-85-0 ) Intshayelelo

I-3-METHYL-5-ISOXAZOLEACETIC ACID i-organic compound kunye ne-chemical formula C6H7NO3. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko:Indalo:
-Imbonakalo: Ikristale emhlophe eqinileyo
-Indawo yokunyibilika: 157-160 ℃
-i-molecular mass mass: 141.13g / mol
-Ukunyibilika: Inyibilika kancinci emanzini, inyibilika etywaleni, ether kunye nezinyibilikisi zendalo
-Iipropati zeKhemikhali: I-3-methyll-5-isoxazoleacetic ACID ingaba ne-acylated, i-carbonylated kwaye ifakwe endaweni ye-ACID-catalyzed reactions.

Sebenzisa:
-Intsimi ye-Pharmaceutical: 3-METHYL-5-ISOXAZOLEACETIC ACID isetyenziswe njenge-synthetic intermediate kwaye isetyenziswa ngokuqhelekileyo ekulungiseleleni iziyobisi kunye nama-molecule asebenzayo.
-Indawo yokubulala izitshabalalisi: Isenokusetyenziswa njengemathiriyeli ekrwada yamayeza okubulala izitshabalalisi, isetyenziselwa ukulungisa imichiza, imichiza yokungunda kunye nemichiza yokutshabalalisa ukhula.

Indlela:
Indlela yokulungiselela i-3-methyll-5-isoxazoleacetic ACID inzima ngakumbi, kodwa inokuqhutywa ngamanyathelo alandelayo:
1. Okokuqala lungiselela i-5-Isoxazolylmethanol (5-Isoxazolylmethanol).
2. Ukusebenzisa i-pyruvic acid (i-Acetone) kunye ne-Potassium nitrate (i-nitrate ye-Potassium) phambi kwe-ion ye-iodide ye-nitration reaction, ukulungiswa kwe-5-Isoxazolylcarboxylic acid (5-Isoxazolylcarboxylic acid).
3. I-Acylation ye-5-isoxazolyl carboxylic ACID isebenzisa i-methanol kunye ne-sulfuric ACID ukuvelisa i-3-METHYL-5-ISOXAZOLEACETIC ACID.

Ulwazi ngoKhuseleko:
Xa uphethe i-3-methyll-5-isoxazoleacetic ACID, kufuneka kuthathwe amanyathelo okhuseleko alandelayo:
-Kuphephe ukudibana nolusu kunye namehlo. Ukuba ukudibana kwenzeka, hlambulula ngokukhawuleza ngamanzi amaninzi.
-Nxiba izixhobo ezifanelekileyo zokuzikhusela njengeeglavu, iiglavu kunye needyasi zelebhu.
-Kuphephe ukuphefumla umphunga okanye uthuli lwalo, kwaye unikeze umoya owaneleyo ngexesha lokusebenza.
-Xa usenza amalungiselelo e-laboratory-scale, landela iinkqubo ezikhuselekileyo zelebhu yeekhemikhali.

  • Ngaphambili:
  • Okulandelayo:
    • Bhala umyalezo wakho apha kwaye uwuthumele kuthi
