Tartaric acids: mis, zog, kev npaj

Tartaric acids - tebchaw uas yog feem ntau pom nyob rau hauv cov nroj tsuag ntiaj teb no. Qhov no yuav ua tau raws li dawb isomers thiab acid ntsev. Lub ntsiab qhov chaw ntawm no substance - siav txiv hmab txiv ntoo ntawm cov txiv hmab. Caw pob zeb txawv soluble poov tshuaj ntsev, tsim thaum lub sij hawm fermentation haus ntawm berries. Qhov no kev noj haus ntxiv yog sau lo rau E334. Tau nws feem ntau yog los ntawm theem nrab ua caw khoom khoom.

Tartaric acid: Formula thiab variations

Tartaric acid yog ib tug hygroscopic muaju uas muaj nuj nqis tsw tsis xim. Txawm li cas los, cov tshuaj yeeb dej caw muaj ib tug hais qaub saj. Tag nrho cov hom ntawm cov tartaric acid yog nkag soluble nyob rau hauv dej thiab nyob rau hauv ethanol. Tebchaw ntau resistant rau aliphatic hydrocarbons, benzene thiab ether. Cov tshuaj mis ntawm lub tebchaw: C ₄ H ₆ O _6.

Tartaric acid tshwm sim nyob rau hauv daim ntawv ntawm cov plaub isomers. Qhov no yog vim lub equilibrium thiab symmetrical arrangement ntawm lub acidic carboxyl, hydrogen ions thiab hydroxyl moieties. Lawv yog:

1. D-tartaric, txawv - tartaric acid.
2. L- tartaric acid.
3. Antivinnaya, nyob rau hauv lwm yam lus - mezovinnaya acid.
4. Txiv hmap acid uas yog ib tug sib tov ntawm tartaric acid thiab L- D-.

lub zog

Tartaric acids zoo tib yam nyob rau hauv tshuaj zog. Txawm li cas los, lawv yog cov heev txawv thiab muaj qhov sib txawv nyob rau hauv lub cev tsis. Piv txwv li, D- thiab L- tartaric acids pib yaj thaum ib tug kub ntawm 140 ° C, grape - los ntawm 240 mus 246 ° C, mezovinnaya acid - 140 ° C.

Nrog kev xav txog solubility, thawj ob lub tebchaw yog cov zoo soluble nyob rau hauv dej, thiab cov seem ob yog resistant rau dej.

Tartaric acid ntsev

Tartaric acid yuav tsim tsuas yog ob tug cov hom ntawm cov ntsev: acidic thiab nruab nrab. Tebchaw ntawm lub yav tas hom yuav tau kiag li yaj nyob rau hauv dej. Txawm li cas los, thaum raus nyob rau hauv lawv cov caustic alkali Rochelle daim ntawv muaju. Acid mono-acid yog tsis zoo soluble nyob rau hauv cov dej. Qhov no muaj xws li tsis tau tsuas yog dej tab sis kuj haus cawv thiab wine khoom. Lawv maj mam tso rau ntawm cov phab ntsa hauv cov hlab ntsha. Tom qab ntawd, tus txheem maj mam muab rho tawm thiab siv los mus ua organic acid.

Raws li rau cov qab zib ntawm tartar, ces nws yog muaj tsis tau tsuas yog nyob rau hauv lub kua txiv ntawm cov txiv hmab txiv hmab txiv ntoo, tab sis kuj nyob rau hauv lub nectars nrog sis plawv hniav thiab pastes ua los ntawm txiv hmab txiv ntoo.

txhua txhua hnub tus nqi

Tartaric acids yuav tsum tau los ntawm lub cev cia li nyob rau hauv kom cov tom qab tawg, kawg ntawm lub digestive system, qhov kev nyuaj siab, raws li tau zoo raws li nrog txo pais plab acidity.

Cov tebchaw yog pom nyob rau hauv acidic txiv hmab txiv ntoo. Qhov siab tshaj plaws concentration ntawm tartaric acid yog feeb meej nyob rau hauv rhubarb, papaya, cranberries, Quince, garnet, lws suav, lub txiv, Currant dub, txiv qaub, txiv kab ntxwv, avocado, mandarins, txiv ntoo qab zib, apples thiab cov txiv hmab.

Nrog kom zoo thiab xuas hnub yuav tsum tau muaj xws tebchaw yog siab them. Rau ib txwm lag luam txiv neej lub cev yuav tsum tau 15 mus rau 20 milligrams ntawm tartaric acid, cov poj niam - los ntawm 13 mus rau 15 milligrams, thiab rau cov me nyuam - ntawm 5 mus rau 12 milligrams.

Qhov tseem ceeb tartaric acid

tartaric acid zog yog ib qhov nyuaj rau overestimate. Qhov no compound muaj ib tug lom tseem ceeb. Tartaric acid:

1. Nws tones lub plawv mob.
2. Ceev cov hlab ntsha.
3. Nws nkoos collagen synthesis.
4. Pab txoj kev ruaj kho uas thiab elasticity ntawm daim tawv nqaij.
5. Nws tiv thaiv oxidation ntawm lub cev hlwb.
6. Nws tsub kom tus nqi ntawm ndlwg ntawm tag nrho cov metabolic dab.
7. Nws reacts nrog radionuclides, thiab accelerates lawv feem.

Thaum ntawm kev siv lub additive yuav tsum coj mus rau hauv tus account uas qhov tshaj ntawm lub hnub yuav tsum tau yog fraught nrog txim. Tej zaum koj yuav muaj kev tshwm sim ntawm overdose, uas muaj xws li tuag tes tuag taw, kiv taub hau, raws plab thiab ntuav. Nyob rau hauv tej rooj plaub, ntev li siv cov reagent yuav ua tau kom neeg tuag taus. Tuag no tshwm sim nyob rau hauv lub sij hawm uas cov tshuaj ntawm tartaric acid yog ntau tshaj 7.5 grams ib 1 kilogram ntawm qhov ceeb thawj.

Nyob rau hauv thiaj li tsis mus ua mob tau rau koj lub cev, ua txhua hnub tus nqi ntawm ib yam khoom nyob ib leeg yog tsis pom zoo. Qhov no yuav ua tau los ntawm cov chaw tus kws kho mob. Tshwj xeeb tshaj yog yog hais tias tus neeg mob yog cov nquag mus herpes, nws muaj cov tawv los yog tau tawg lub mechanism ntawm assimilation ntawm tej yam acids.

Daim ntawv thov nyob rau hauv cov zaub mov kev lag luam

Tartaric acid, cov mis uas muaj cov saum toj no dab yuav qeeb tus lwj thiab lwj cov khoom. Vim cov cuab yeej no, ib tug compound lug siv nyob rau hauv lub lag luam ua noj. Tartaric acid tiv thaiv ntxov ntxov txhob lwj ntawm hmoov, raws li zoo raws li kaus poom zaub mov. Heev feem ntau, cov compound yog siv raws li ib tug antioxidant reagent los yog acidity regulator.

Nyob rau hauv nyob tus yeees ntawm haus dej haus cawv, cov lus dej, bakery thiab confectionery khoom, kaus poom khoom thiab tartaric acid yog tam sim no. Kev npaj ntawm cov tivthaiv - ib tug yooj yim txheej txheem. Rau lub hom phiaj no, pov tseg generated raws li ib tug tshwm sim ntawm cawu cub haus.

Nws yog ib nqi sau cia hais tias lub substrate siv rau lub preservation ntawm whiteness thiab plasticity ntawm qhob noom xim kasfes, luag whipped cov nqaijrog, raws li zoo raws li plam lub khob noom cookie. Nyob rau hauv tas li ntawd, lub additive E334 tso cai rau koj mus soften lub saj ntawm dej cawv haus cawv txiv hmab, uas ua rau lawv ntau tart thiab qab ntxiag.

Kev siv ntawm tartaric acid nyob rau hauv lwm qhov chaw

Tartaric acid yog dav siv tsis tau tsuas yog nyob rau hauv cov zaub mov kev lag luam, tab sis kuj nyob rau hauv pharmaceuticals. Nyob rau hauv kev kho mob daim ntaub ntawv rau lub compound yog siv raws li ib tug pab tivthaiv. Nws yog siv nyob rau hauv qhuav ntawm soluble tshuaj, cov tshuaj ntaus cev yam tshuaj, raws li zoo raws li effervescent ntsiav tshuaj.

Tartaric acid yog siv nyob rau hauv cosmetology. Qhov no compound yog ib feem ntawm ntau kev zawv plaub hau, muab tshuaj pleev, cream thiab peelings npaj rau kev tu plaub hau thiab tej tawv nqaij.

Nyob rau hauv qhov tseeb, tartaric acid siv nyob rau hauv ntau lub teb. Piv txwv li, lub compound siv nyob rau hauv lub textile kev lag luam rau kho cov xim los ntawm dyeing. Nyob rau hauv kev tsim kho ntawm lub additive yog siv raws li ib tug reagent. Nws yog ntxiv rau cov plaster thiab xis mas mixtures. Nrog rau qhov no loj hardens qeeb qeeb.

Rochelle lub ntsev yog siv nyob rau hauv qhov siv thiab ua cov computers, loudspeakers thiab microphones, vim hais tias ntawm nws cov piezoelectric zog.
