I-D(-)-I-asidi yeTartaric/ I-CAS：526-83-0

Ukusetyenziswa

Intshayelelo: Ngenxa yokuba imolekyuli ye-tartaric acid inee-athomu ezimbini zekhabhoni ezingafaniyo, inee-isomers ezintathu ze-optical, ezizezi i-dextrorotatory tartaric acid [L(+) -tartaric acid], i-levorotatory tartaric acid [D(-) -tartaric acid] kunye ne-racemic tartaric acid (Meso). Izixa ezilinganayo ze-L-tartaric acid kunye ne-D-tartaric acid zixutywa ukuze kufunyanwe i-racemic tartaric acid okanye i-DL-tartaric acid. I-L-tartaric acid kunye ne-d-tartaric acid zii-enantiomers. Zonke i-tartaric acid ezivela ngokwemvelo ziyi-dextrorotatory. Ayinambala iikristale ezicacileyo okanye i-white fine to granular crystalline powder. Imveliso ye-crystalline inemolekyuli enye yamanzi e-crystalline, ayinavumba, izinzile emoyeni, inencasa emuncu, enomlinganiselo womuncu we-0.0025%, kwaye ubunzulu bomuncu bumalunga ne-1.2 ukuya kwi-1.3 ye-citric acid. Inencasa ethambileyo kancinci kwaye inika ivumba elifana neleswekile eyosiweyo xa itshisiwe. Ikwanayo nefuthe lokucheba kwi-ion zesinyithi. I-1g inyibilika malunga ne-0.8mL yamanzi (kwi-25℃), i-0.5mL yamanzi abilayo, kunye ne-3mL ye-ethanol. I-pH yesisombululo samanzi esingu-0.3% yi-2.4.

I-tartaric acid yi-carboxylic acid ekhoyo kwizityalo ezininzi, ezifana neediliya kunye ne-tamarind, kwaye ikwayenye yezona asidi ziphambili ze-organic kwiwayini. I-tartaric acid, njenge-antioxidant eyongezwa ekutyeni, inokunika ukutya incasa emuncu. I-tartaric acid ifana ne-citric acid kwaye ingasetyenziswa kwishishini lokutya, njengakwimveliso yeziselo. I-tartaric acid, xa isetyenziswa kunye ne-tannin, inokusebenza njenge-mordant kwiidayi ze-asidi. I-tartaric acid inokuxubana nee-ion ezahlukeneyo zesinyithi kwaye ingasetyenziswa njenge-arhente yokucoca kunye ne-arhente yokupolisha kwiindawo zesinyithi.

I-asidi yeTartaric, ekwaziwa ngokuba yi-2, 3-dihydroxysuccinic acid, i-dihydroxysuccinic acid, kunye ne-gluconic acid, inee-isomers ezintathu ze-optical ngenxa yokubakho kwee-athomu ezimbini zekhabhoni ezifanayo kwimolekyuli yayo. I-asidi yeTartaric iquka i-asidi ye-D-tartaric, i-asidi ye-L-tartaric, kunye ne-asidi ye-DL-tartaric. I-asidi yeTartaric yikristale ye-prismatic okanye umgubo ongenambala, ocacileyo onencasa enamandla emuncu kunye nencasa encinci. Iyanyibilika emanzini kwaye ikhona kakhulu kwizityalo ezahlukeneyo kwindalo ngohlobo lweetyuwa ze-potassium okanye ze-calcium, apho iidiliya zinomxholo ophezulu. I-asidi yeTartaric iveliswa kwiikristale ezityheli ezibekwe ezantsi kweebharele ngexesha lokwenza iwayini, yiyo loo nto ibizwa ngokuba yi-asidi ye-tartaric. Ubumuncu bayo buphindwe kayi-1.3 kunobo be-asidi ye-citric. Ukusetyenziswa kwayo kufana noko kwe-asidi ye-citric. Iyanyibilika kakhulu emanzini, ngoko ke ifanelekile ekwenzeni iziselo ezifuthayo. Iikristale ze-tartaric acid ziqulathe imolekyuli enye yamanzi acwebezelayo, azinavumba, zizinzile emoyeni, zinencasa emuncu, zinomlinganiselo wobumuncu we-0.0025%, kwaye ubunzulu bobumuncu bumalunga ne-1.2 ukuya kwi-1.3 ye-citric acid. Zinencasa ethambileyo kancinci kwaye zikhupha ivumba elifana neleswekile eyosiweyo xa itshisiwe. Zikwanefuthe le-chelating kwi-ions zesinyithi. I-1g inyibilika malunga ne-0.8mL yamanzi (kwi-25℃), i-0.5mL yamanzi abilayo, kunye ne-3mL ye-ethanol. I-pH yesisombululo samanzi esingu-0.3% yi-2.4. I-Dl-tartaric acid isetyenziswa kakhulu njengesongezelelo sokutya, iipilisi ze-vitamin C effervescent, kunye ne-arhente ye-acidifying eyenza ityuwa (i-choline tartrate) kwiziyobisi ze-alkali zendalo, njl. I-Tartaric acid inokwenza iityuwa ze-acid kunye neetyuwa ezingathathi cala ezineziseko. Umzekelo, yinciphise nge-potassium hydroxide ukwenza i-potassium hydrogen tartrate. Le yokugqibela ingaphinda icutshungulwe ibe yi-potassium antimony tartrate (oko kukuthi, * i-tartrate) kunye ne-sodium potassium tartrate. Ingasetyenziselwa ukuvelisa iityuwa ezifana ne-sodium hydrogen tartrate, i-sodium tartrate kunye ne-ammonium tartrate. Ngokwe-GB2760-86 yelizwe lethu, i-tartaric acid ingasetyenziswa njenge-acidulant kwizongezo zokutya, kwaye isetyenziswe kwiziselo ezibandayo, iijam, iziselo, ijeli, ukutya okusemathinini kunye neelekese. Ngenxa yokuba iphantsi kwe-hygroscopicity kunye nozinzo oluhle, ifanelekile ngokukodwa kwijusi yeziqhamo kunye neziselo eziqinileyo. Ikwasetyenziswa njenge-emulsifier yokutya kunye ne-chelating agent, kunye ne-antioxidant enhancer. Izicoci kunye neepolishi zesinyithi; Izinto eziluhlaza zamayeza, ii-mordants, njl. Idla ngokusetyenziswa kunye ne-citric acid, i-malic acid, njl. Umda wokutya okumnandi yi-2% (eJapan) kunye ne-4% (e-United States). Amanyathelo okusebenzisa: Le mveliso inencasa enamandla emuncu kwaye inamandla okubamba kancinci. Idla ngokusetyenziswa kunye nezinye ii-asidi. Isetyenziswa kakhulu ekulungiseleleni iziselo kunye nokunye ukutya okunencasa yeediliya. Ububanzi bokusetyenziswa kunye nomlinganiselo: Ingasetyenziswa kukutya okwahlukeneyo ngobuninzi obufanelekileyo njengoko kufuneka kwimveliso. Isalathiso sokusetyenziswa: Xa isetyenziselwa iijam kunye neejeli, kuyacetyiswa ukuba igcine i-pH yemveliso kwi-2.8 ukuya kwi-3.5. Ihlala isetyenziswa kunye ne-citric acid, i-malic acid, njl. Le mveliso ingasetyenziswa ngobuninzi obufanelekileyo kwiilekese nakwiimpahla ezibhakiweyo, njl.
