I-Glyoxylic acid CAS 298-12-4, ine-formula ye-molecular ye-C₂H₂O₃ kunye ne-molecular weight of 74.04. Isisombululo sayo samanzi lulwelo olungenambala olucacileyo, lunyibilika kancinane kwi-ethanol, i-ether kunye ne-benzene.

Glyoxylic acidyinto ebalulekileyo ye-organic compound, equkethe iqela le-aldehyde (-CHO) kunye neqela le-carboxyl (-COOH), kunye ne-formula yesakhiwo se-HOCCOOH. Uneentlobo ezahlukeneyo zezinto ezibonakalayo kunye neekhemikhali, ezifana nobuninzi bobudlelwane (d₂₀₄) be-1.384, i-refractive index (n₂₀D) ye-1.403, indawo yokubilisa ye-111 ° C, i-melting point -93 ° C, i-flash point ye-103.0 ° C kunye ne-103.9 ° C yoxinzelelo lwe-3. 25°C. Kubonakala njengeekristale ezimhlophe kunye nevumba elibi. Isisombululo sayo esinamanzi silulwelo olungenambala okanye olumthubi olukhanyayo, olunganyibilikiyo kwi-ether, ethanol nakwibenzene. Iyakwazi ukufunxa ukufuma kwaye ibe ludaka ngexesha elifutshane emva kokuvezwa emoyeni, kwaye iyadleka.

I-Glyoxylic acid CAS 298-12-4inoluhlu olubanzi losetyenziso kwiindawo ezahlukeneyo:

Indawo yokuthambisa:Glyoxylic acidisetyenziswa njenge-perfumer kunye ne-fixative kwi-cosmetics kwi-cosmetic field.

Indawo yoXhobo:I-Glyoxylic acid yimathiriyeli ekrwada yokwenziwa ye-pharmaceutical intermediates efana ne-antihypertensive drug atenolol kunye ne-Dp-hydroxyphenylglycine. I-Glyoxylic acid ingasetyenziselwa ukwenza i-penicillin yomlomo, i-allantoin, i-p-hydroxyphenylglycine, i-p-hydroxyphenylacetic acid, i-mandelic acid, i-acetophenone, i-α-thiophene glycolic acid, i-p-hydroxyphenylacetamide (isifo senhliziyo kunye ne-hypertension ye-hypertension njenge-atenolol). Ngelo xesha, isetyenziselwa ukuvelisa iimveliso zamachiza ezichasayo ezifana ne-capsule kunye ne-allantoin.

Ezolimo:Oosonzululwazi baphuhlise iplastiki eyenziwe ngebiomass ukuze ithathe indawo yeeplastiki zesintu. Le plastiki intsha yenziwe ngeekhemikhali ezingabizi kakhulu, apho iasidi ye-glyoxylic inokudibanisa iimolekyuli zeswekile kunye namaqela "ancamathelayo" ukuze asebenze njengebhloko yokwakha yeplastiki. Kwintsimi yezolimo, le plastiki intsha inokusetyenziswa kwizinto ezahlukeneyo ezifana nokupakishwa, amalaphu, amayeza kunye neemveliso zombane.

Ukhuseleko lokusingqongileyo:Umjikelo we-glyoxylate ubaluleke kakhulu kwinkalo ye-biochemistry. Ngokukodwa kwindawo engenakukhanya, izityalo ziyakwazi ukuguqula i-acids e-fatty ibe yiswekile ngokusebenzisa umjikelezo we-glyoxylate ukuze kugcinwe amandla kunye nomthombo wekhabhoni ofunekayo ekukhuleni, ukukhuthaza umjikelezo wezinto eziphilayo, kunye nokuphucula ukukwazi ukuziqhelanisa neendawo ezimbi ezifana nesomiso kunye netyuwa ephezulu.

UbudengeyiiGlyoxylic acid yobungcali CAS 298-12-4 umenzi, sinokubonelela ngeentlobo ngeentlobo zengcaciso yemveliso yeI-Organic Chemistry, ukuqinisekiswa komgangatho, ukuhanjiswa ngokukhawuleza, kunesitokhwe. Ukuba uyayifuna, ncedaQhagamshelana nathi.
