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

I-3-METHYL-5-ISOXAZOLEACETIC ACID iyinhlanganisela ye-organic ene-chemical formula C6H7NO3. Okulandelayo yincazelo yobunjalo bayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:Imvelo:
-Ukubukeka: I-crystalline emhlophe eqinile
-Indawo yokuncibilika: 157-160 ℃
-isisindo samangqamuzana esihlobene: 141.13g/mol
-Ukunyibilika: Kuncibilika kancane emanzini, kuncibilika otshwaleni, ether nasezincibilikisini eziphilayo
-Izakhiwo zamakhemikhali: I-3-methyll-5-isoxazoleacetic ACID ingaba i-acylated, i-carbonylated futhi ifakwe esikhundleni se-ACID-catalyzed reactions.

Sebenzisa:
-Inkundla yezemithi: I-3-METHYL-5-ISOXAZOLEACETIC ACID isetshenziswa njenge-synthetic intermediate futhi ivame ukusetshenziswa ekulungiseni izidakamizwa kanye nama-molecule asebenzayo.
-Insimu yezibulala-zinambuzane: Ingasetshenziswa futhi njengento eluhlaza yezibulala-zinambuzane, esetshenziselwa ukulungisa izibulala-zinambuzane, izibulala-sikhunta kanye nezibulala-khula.

Indlela:
Indlela yokulungiselela i-3-methyll-5-isoxazoleacetic ACID iyinkimbinkimbi kakhulu, kodwa ingenziwa ngezinyathelo ezilandelayo:
1. Okokuqala lungiselela i-5-Isoxazolylmethanol (5-Isoxazolylmethanol).
2. Ukusebenzisa i-pyruvic acid (i-Acetone) ne-Potassium nitrate (i-Potassium nitrate) phambi kwe-ion ye-iodide yokusabela kwe-nitrate, ukulungiswa kwe-5-Isoxazolylcarboxylic acid (5-Isoxazolylcarboxylic acid).
3. I-Acylation ye-5-isoxazolyl carboxylic ACID isebenzisa i-methanol ne-sulfuric ACID ukukhiqiza i-3-METHYL-5-ISOXAZOLEACETIC ACID.

Ulwazi Lokuphepha:
Lapho uphatha i-3-methyll-5-isoxazoleacetic ACID, kufanele kuthathwe izinyathelo zokuphepha ezilandelayo:
-Gwema ukuthinta isikhumba namehlo. Uma kwenzeka ukuthintana, hlambulula ngokushesha ngamanzi amaningi.
-Gqoka izinto zokuzivikela ezifanele njengezibuko, amagilavu ​​namajazi elebhu.
-Gwema ukuhogela umhwamuko noma uthuli lwawo, futhi unikeze umoya owanele ngesikhathi sokusebenza.
-Lapho wenza amalungiselelo esikali selabhorethri, landela izinqubo eziphephile zelabhorethri yamakhemikhali.
