Kushandiswa
Nhanganyaya: Nekuti tartaric acid molecule ine maatomu maviri akafanana ecarbon asymmetric, ine maisomers matatu e optical, anoti dextrorotatory tartaric acid [L(+) -tartaric acid], levorotatory tartaric acid [D(-) -tartaric acid] uye racemic tartaric acid (Meso). Huwandu hwakaenzana hweL-tartaric acid neD-tartaric acid zvinosanganiswa kuti zviwane racemic tartaric acid kana DL-tartaric acid. L-tartaric acid ned-tartaric acid ma enantiomers. All tartaric acid inowanikwa zvakasikwa idextrorotatory. Iine makristaro asina ruvara kana kuti upfu hwe crystalline hwakatsetseka. Chigadzirwa che crystalline chine molecule imwe yemvura ye crystalline, haina hwema, inogara mumhepo, ine kuravira kwakavava, ine chiyero chekuvava che 0.0025%, uye kusimba kwekuvava kunenge ka1.2 kusvika 1.3 kupfuura citric acid. Ine kuravira kunorwadza zvishoma uye inonhuwa sekweshuga yakakangwa kana yapiswa. Inewo simba rekucheka pasimbi. 1g inonyungudutswa mu 0.8mL yemvura (pa25℃), 0.5mL yemvura inopisa, uye 3mL yeethanol. pH ye 0.3% aqueous solution i2.4.
tartaric acid iasidhi ine kabhoksiliki inowanikwa mumiti yakawanda, yakadai semazambiringa netamarind, uye ndeimwe yemaasidhi makuru eorganic ari muwaini. Tartaric acid, seantioxidant inowedzerwa muchikafu, inogona kupa chikafu kuravira kwakavava. Tartaric acid yakafanana ne citric acid uye inogona kushandiswa muindasitiri yechikafu, senge mukugadzira zvinwiwa. Tartaric acid, kana ikashandiswa pamwe chete ne tannin, inogona kushanda se mordant yeacid dyes. Tartaric acid inogona kusanganiswa nemaion akasiyana-siyana esimbi uye inogona kushandiswa semushonga wekuchenesa uye wekupukuta pamusoro pesimbi.
Tartaric acid, inozivikanwawo se2, 3-dihydroxysuccinic acid, dihydroxysuccinic acid, uye gluconic acid, ine maisomers matatu e optical nekuda kwekuvapo kwemaatomu maviri akafanana ecarbon asymmetric mumorekuru yayo. Tartaric acid inosanganisira D-tartaric acid, L-tartaric acid, uye DL-tartaric acid. Tartaric acid ikristaro isina ruvara, yakajeka yeprismatic kana upfu ine kuravira kwakasimba kwekuvava uye kuravira kudiki. Inonyungudika mumvura uye inowanikwa zvakanyanya mumiti yakasiyana-siyana muchimiro chepotassium kana calcium salts, ine mazambiringa ane huwandu hwakawanda. Tartaric acid inogadzirwa kubva kumakristaro eyero akaiswa pasi pemabara panguva yekugadzira waini, saka inonzi tartaric acid. Kuvava kwayo kunopfuura ka1.3 kupfuura citric acid. Mashandisirwo ayo akafanana nea citric acid. Inonyungudika zvakanyanya mumvura, saka yakakodzera kugadzira zvinwiwa zvine furo. Makristaro eTartaric acid ane molecule imwe chete yemvura ine crystalline, haana hwema, anogara ari mumhepo, ane kuravira kwekuvava, ane chiyero chekuvava che0.0025%, uye simba rekuvava rinopetwa ka1.2 kusvika 1.3 kupfuura citric acid. Ane kuravira kunorwadza zvishoma uye anonhuwa kwakafanana neshuga yakakangwa kana yapiswa. Anewo chelating effects pasimbi ions. 1g inonyungudutswa mu0.8mL yemvura (pa25℃), 0.5mL yemvura inopisa, uye 3mL yeethanol. pH ye 0.3% aqueous solution i2.4. Dl-tartaric acid inoshandiswa zvakanyanya sechikafu chinowedzera, mapiritsi e vitamin C effervescent, uye munyu-forming acidifying agent (choline tartrate) yemishonga ye organic alkali, nezvimwewo. Tartaric acid inogona kugadzira acid salts uye neutral salts ine mabhesi. Semuenzaniso, isa ne potassium hydroxide kuti igadzire potassium hydrogen tartrate. Iyo yekupedzisira inogona zvakare kugadziriswa kuita potassium antimony tartrate (kureva, * tartrate) uye sodium potassium tartrate. Inogona zvakare kushandiswa kugadzira munyu wakaita sesodium hydrogen tartrate, sodium tartrate uye ammonium tartrate. Sekureva kweGB2760-86 yenyika yedu, tartaric acid inogona kushandiswa seacidulant mune zvinowedzerwa muchikafu, uye inoshandiswa muzvinwiwa zvinotonhora, jamu, zvinwiwa, jelly, chikafu chemumagaba uye masiwiti. Nekuda kwekusagadzikana kwayo kwakaderera uye kugadzikana kwakanaka, inonyanya kukodzera muto wemichero nezvinwiwa zvakasimba. Inoshandiswawo sechikafu chinosanganisa uye chelating agent, pamwe neantioxidant enhancer. Zvishandiso zvekuchenesa nekuchenesa simbi; Zvekushandisa zvemishonga, mordants, nezvimwewo. Inowanzo shandiswa pamwe chete necitric acid, malic acid, nezvimwewo. Muganho muzvikafu zvinotapira i2% (Japan) uye 4% (United States). Kuchenjerera kushandiswa: Chigadzirwa ichi chine kuravira kwakasimba kwekuvava uye chinobata zvishoma. Chinowanzo shandiswa pamwe chete nedzimwe acids. Inonyanya kushandiswa pakugadzira zvinwiwa nezvimwe zvekudya zvine kuravira kwemazambiringa. Huremu hwekushandiswa uye huwandu: Inogona kushandiswa muzvikafu zvakasiyana-siyana nehuwandu hwakakodzera sezvinodiwa pakugadzirwa. Kushandiswa kunoshanda: Kana ichishandiswa pajamu nejellies, zvinokurudzirwa kuchengetedza pH yechigadzirwa pa2.8 kusvika 3.5. Inowanzo shandiswa pamwe chete necitric acid, malic acid, nezvimwewo. Chigadzirwa ichi chinogonawo kushandiswa nehuwandu hwakakodzera mumaswiti nezvinhu zvakabikwa, nezvimwewo.
Kurongedza uye Kutumira
25KG/Drum kana zvichienderana nezvinodiwa nevatengi.
Ndezvezvinhu zvakajairika uye zvinogona kutumirwa negungwa nemhepo
Chengeta uye chengeta
Nguva yesherufu: Mwedzi makumi maviri nemana kubva pazuva rekugadzirwa kwayo, yakachengetwa munzvimbo inotonhorera yakaoma isina chiedza chezuva, mvura.
Imba yekuchengetera zvinhu ine mhepo, Inoomesa zvinhu zvishoma, Yakaparadzaniswa nezvinokonzera makemikari, maasidhi.
