Qhov zoo ntawm DL-Tartaric acid

Cim qaub saj yam ntxwv

Raws li tus neeg sawv cev qaub hauv kev lag luam khoom noj khoom haus, DL-tartaric acid muaj lub zog qaub dua li citric acid thiab tuaj yeem ua rau muaj kev paub qab zib ntau dua rau cov khoom lag luam, uas yog ib qho tseem ceeb uas txawv ntawm cov khoom qaub xws li citric acid.

Zoo hlau complexation muaj peev xwm

Hauv kev lag luam tshuaj, DL-tartaric acid muaj peev xwm ua kom cov hlau zoo heev. Qhov no complex muaj peev xwm pab txhim kho cov synthesis thiab stability ntawm tej yam tshuaj, piv txwv li, nyob rau hauv ib co tshuaj kho mob hnyav hlau lom, DL-tartaric acid yuav complex nrog hnyav hlau ions los txhawb lawv excretion los ntawm lub cev.

Sib npaug ntawm stability thiab reactivity

Hais txog cov khoom siv tshuaj, DL-tartaric acid qhia tau tias muaj kev ruaj ntseg zoo nyob rau hauv qee yam mob thiab muaj qhov tsim nyog reactivity tib lub sijhawm. Nws muaj qee qhov kev ua siab ntev rau cov cua sov thiab cov kua qaub thiab alkali, thiab hauv qee cov txheej txheem tsim khoom uas xav tau qhov kub thiab txias los yog acid thiab alkali ib puag ncig, nws muaj peev xwm tswj tau nws tus kheej cov khoom siv tshuaj thiab tsis yooj yim rau decompose lossis deteriorate. Kev ruaj ntseg ntawm DL-tartaric acid ua rau nws ua lub luag haujlwm hauv qhov kub thiab txias, acid- puag ncig txheej txheem xws li kev ua zaub mov thiab tshuaj synthesis.

Chirality thiab cov yam ntxwv ua haujlwm kho qhov muag (hauv cov ntawv thov tshwj xeeb)

Txawm hais tias DL-tartaric acid yog racemic thiab tsis ua haujlwm optically, nws tuaj yeem siv los ua cov khoom pib lossis cov khoom siv pabcuam hauv qee thaj chaw uas muaj chiral synthesis lossis kev kawm txog cov khoom siv kho qhov muag. Hauv asymmetric synthesis, DL-tartaric acid tuaj yeem hloov mus rau hauv optically active tartaric acid derivatives los ntawm cov tshuaj tiv thaiv tshwj xeeb thiab kev sib cais, uas yog siv los npaj cov tshuaj chiral thiab chiral catalysts, thiab lwm yam, muab cov khoom siv tseem ceeb rau kev tshawb fawb thiab tsim cov chiral compounds.

Cov khoom siv

Kev siv DL-Tartaric acid CAS 133-37-9

Organic acid series khoom los ntawm Shandong Sparrow Chemical CO., LTD

Tus neeg ua kua qaub

Nws yog feem ntau siv los ua zaub mov nrog qaub saj, xws li kua txiv hmab txiv ntoo, dej qab zib, txiv hmab txiv ntoo jams thiab ntau yam khoom qab zib.

Txoj cai ntawm kev ua:

Lub hauv paus ntsiab lus ntawm DL-tartaric acid raws li tus neeg sawv cev qaub yog nyob ntawm nws lub peev xwm los ionize hydrogen ions, uas txhim kho tsw los ntawm kev kho pH nqi.
Dl-tartaric acid yog binary organic acid nrog ob pawg carboxyl (-COOH) thiab muaj peev xwm ionize hydrogen ions (H⁺) hauv cov tshuaj aqueous, yog li txo cov pH ntawm cov tshuaj thiab muab cov qaub saj.

Tus neeg sawv cev

Nws feem ntau yog siv los ua cov khoom noj crispy lossis fluffy, xws li ncuav mog qab zib, qhob cij thiab ncuav qab zib.

Txoj cai ntawm kev ua:

Raws li tus neeg sawv cev leavening, DL-tartaric acid feem ntau tsim cov pa roj carbon dioxide los ntawm kev hnov mob nrog sodium bicarbonate kom nthuav cov ntim thiab soften cov khoom noj.
Qhov sib npaug ntawm cov tshuaj tiv thaiv yog raws li nram no:
C₄H₆O₆+2NaHCO₃→C₄H₄O₆Na₂+2CO₂+2H₂O
Tsis tas li ntawd, DL-tartaric acid, raws li cov khoom siv acidic, kuj tuaj yeem txo cov pH nqi ntawm lub khob noom cookie, txhim kho cov kev mob fermentation, thiab txhim kho cov nyhuv o.

Kev kho mob hnyav hlau lom

Daim ntawv thov ntawm DL-tartaric acid nyob rau hauv kev kho mob hnyav hlau lom yog feem ntau raws li nws chelation, uas yog, los ntawm kev tsim ib tug ruaj khov dej-soluble complex nrog hnyav hlau ions los txhawb kev tshem tawm ntawm hnyav hlau los ntawm lub cev.

Cov carboxyl (-COOH) thiab hydroxyl (-OH) pawg hauv DL-tartaric acid tuaj yeem tsim cov dej ruaj khov-soluble complexes nrog hnyav hlau ions, xws li Pb²⁺ thiab Hg²⁺.
Qhov sib npaug ntawm cov tshuaj tiv thaiv yog raws li nram no:
C₄H₆O₆+M²⁺→C₄H₄O₆M+2H⁺
(M²⁺ sawv cev rau cov hlau hnyav, xws li Pb²⁺ thiab Hg²⁺)
