Ojiji

Okwu Mmalite: Ebe ọ bụ na molekul tartaric acid nwere atọm carbon abụọ yiri nke ahụ, o nwere isomers optic atọ, ya bụ dextrorotatory tartaric acid [L(+) -tartaric acid], levorotatory tartaric acid [D(-) -tartaric acid] na racemic tartaric acid (Meso). A na-agwakọta L-tartaric acid na D-tartaric acid nhata iji nweta racemic tartaric acid ma ọ bụ DL-tartaric acid. L-tartaric acid na d-tartaric acid bụ enantiomers. Tartaric acid niile na-apụta n'okike bụ dextrorotatory. Ọ bụ kristal na-enweghị agba ma ọ bụ ntụ ntụ kristal ọcha ruo na granular. Ngwaahịa kristal ahụ nwere otu molekul mmiri kristal, enweghị isi, kwụsiri ike n'ikuku, nwere uto gbara ụka, yana oke gbara ụka nke 0.0025%, ike gbara ụka dịkwa ihe dị ka ugboro 1.2 ruo 1.3 nke citric acid. Ọ na-enwe ntakịrị ụtọ na-eme ka ọ na-esi ísì ọjọọ ma na-esi ísì ọjọọ yiri shuga a ṅara n'ọkụ mgbe a gbara ya ọkụ. Ọ na-enwekwa mmetụta na-eme ka ọ na-esi ísì ọjọọ na ion ígwè.

Acid tartaric bụ carboxylic acid dị n'ọtụtụ osisi, dịka mkpụrụ vaịn na tamarind, ọ bụkwa otu n'ime asịd organic kachasị dị na mmanya. Acid Tartaric, dịka ihe na-egbochi antioxidant nke a na-agbakwunye na nri, nwere ike inye nri ụtọ gbara ụka. Acid Tartaric yiri citric acid ma enwere ike iji ya na ụlọ ọrụ nri, dịka n'imepụta ihe ọṅụṅụ. Acid Tartaric, mgbe ejiri ya na tannin, nwere ike ịbụ ihe na-eme ka agba acid sie ike. Acid Tartaric nwere ike ịdị mgbagwoju anya na ion ígwè dị iche iche ma enwere ike iji ya dị ka ihe nhicha na ihe na-eme ka ọ dị ọcha maka elu ígwè.

Acid Tartaric, nke a makwaara dịka 2, 3-dihydroxysuccinic acid, dihydroxysuccinic acid, na gluconic acid, nwere isomers optic atọ n'ihi na enwere atọm carbon abụọ yiri nke ahụ na molekul ya. Acid Tartaric gụnyere D-tartaric acid, L-tartaric acid, na DL-tartaric acid. Acid Tartaric bụ kristal ma ọ bụ ntụ ntụ prismatic na-enweghị agba, nke na-enwu gbaa nke nwere uto siri ike na obere ụtọ. Ọ na-agbaze na mmiri ma dị n'ọtụtụ osisi n'ụdị potassium ma ọ bụ calcium salts, yana mkpụrụ vaịn nwere nnukwu ọdịnaya. A na-emepụta Tartaric acid site na kristal odo edobere n'ala gbọmgbọm n'oge a na-eme mmanya, ya mere aha ya bụ tartaric acid. Mmiri ya dị ihe dị ka okpukpu 1.3 nke citric acid. Ojiji ya yiri nke citric acid. Ọ na-agbaze nke ukwuu na mmiri, yabụ ọ dabara adaba maka ime ihe ọṅụṅụ na-afụ ụfụfụ. Kristal Tartaric acid nwere otu molekul mmiri kristal, ha enweghị isi, ha kwụsiri ike n'ikuku, ha nwere uto gbara ụka, ha nwere oke mmiri gbara ụka nke 0.0025%, ike mmiri gbara ụka dịkwa ihe dị ka okpukpu 1.2 ruo 1.3 nke citric acid. Ha nwere uto na-afụ ụfụ ntakịrị ma na-esi isi yiri shuga a ṅara n'ọkụ mgbe a gbara ha ọkụ. Ha nwekwara mmetụta na-eme ka ha dị nro na ion ígwè. A na-agbaze 1g n'ime mmiri 0.8mL (na 25℃), 0.5mL nke mmiri ọkụ, na 3mL nke ethanol. pH nke mmiri mmiri 0.3% bụ 2.4. A na-eji Dl-tartaric acid eme ihe dị ka ihe mgbakwunye nri, mbadamba vitamin C na-eme ka ọ dị nro, na ihe na-eme ka ọ dị nro (choline tartrate) maka ọgwụ alkali organic, wdg. Tartaric acid nwere ike ịmepụta nnu acid na nnu na-anọpụ iche nwere ntọala. Dịka ọmụmaatụ, mee ka ọ dị nro na potassium hydroxide iji mepụta potassium hydrogen tartrate. A pụkwara iji nke ikpeazụ mee potassium antimony tartrate (ya bụ, * tartrate) na sodium potassium tartrate. A pụkwara iji ya mepụta nnu dịka sodium hydrogen tartrate, sodium tartrate na ammonium tartrate. Dịka GB2760-86 nke mba anyị si kwuo, enwere ike iji tartaric acid dị ka acidulant na ihe mgbakwunye nri, a na-etinyekwa ya na ihe ọṅụṅụ oyi, jam, ihe ọṅụṅụ, jelii, nri mkpọ na swiit.
