xov xwm

Glyoxylic acidyog ib qho tseem ceeb organic compound nrog ob pawg aldehyde thiab carboxyl, thiab yog dav siv nyob rau hauv kev lag luam chemical engineering, tshuaj, thiab tshuaj tsw qab. Glyoxylic acid CAS 298-12-4 yog dawb crystalline hmoov nrog ib tug pungent tsw. Hauv kev lag luam, nws feem ntau muaj nyob rau hauv daim ntawv ntawm cov tshuaj aqueous (tsis muaj xim lossis daj daj ua kua). Lub melting point ntawm daim ntawv anhydrous yog 98 ℃, thiab cov hemihydrate yog 70-75 ℃.

Pharmaceutical teb: Core intermediates

Kev npaj cov tshuaj ntawm daim tawv nqaij: Glyoxylic acid muaj lub luag haujlwm ntawm kev txhawb nqa kev kho ntawm tes thiab ua kom lub qhov txhab zoo, thiab yog siv dav hauv cov tshuaj pleev, tshuaj pleev qhov ncauj, cov khoom tu tawv nqaij, thiab lwm yam.

Synthetic amino acid derivatives: Glyoxylic acid yog siv los tsim cov derivatives ntawm cov amino acids xws li phenylalanine thiab serine, uas yog cov khoom tseem ceeb hauv biopharmaceuticals thiab cov khoom noj khoom haus.

Kev lag luam tshuaj tsw qab: Feem ntau siv hluavtaws fragrances

Vanillin:Glyoxylic acidthiab guaiacol undergo condensation, oxidation thiab lwm yam kev cuam tshuam los tsim vanillin. Vanillin yog ib qho ntawm cov khoom siv hluavtaws tshaj plaws nyob hauv lub ntiaj teb thiab yog siv los txhim kho qhov tsw ntawm cov khoom noj ( ncuav mog qab zib, dej haus), tshuaj pleev ib ce thiab luam yeeb.

Glyoxylic acid tuaj yeem hnov ​​mob nrog catechol los ua ke glyoxylic acid, uas muaj cov ntxhiab tsw qab thiab tsw qab thiab siv rau cov tshuaj tsw qab, xab npum thiab khoom qab zib. Nws yog ib qho tseem ceeb ntawm floral fragrances.

Lwm cov txuj lom: glyoxylic acid kuj tuaj yeem siv los ua ke ntawm raspberry ketone (fruity aroma type), coumarin (vanilla aroma type), thiab lwm yam., enriching hom thiab flavors ntawm txuj lom.

Hauv kev siv tshuaj tua kab: Kev tsim cov tshuaj tua kab muaj txiaj ntsig zoo

Tshuaj tua kab mob: koom nrog hauv kev sib txuas ntawm glyphosate (ib qho dav-spectrum tshuaj tua kab), glyphosate tuaj yeem tua cov nroj tsuag zoo thiab siv dav hauv kev ua liaj ua teb, horticulture thiab lwm yam.

Tshuaj tua kab: Glyoxylic acid yog siv los npaj quintiaphosphate (organophosphorus insecticide), uas muaj kev tswj tau zoo ntawm cov kab tsuag ntawm cov qoob loo xws li nplej thiab paj rwb (xws li aphids), thiab tsis tshua muaj toxicity thiab residue.

Fungicides: Glyoxylic acid yog siv los ua ib qho nruab nrab los ua ke qee yam heterocyclic fungicides rau kev tswj cov kab mob fungal hauv cov qoob loo.

Lub teb ntawm chemical engineering thiab cov ntaub ntawv

Dej purifying tus neeg sawv cev: Reacts nrog phosphorous acid thiab lwm yam tshuaj los tsim hydroxyphosphonocarboxylic acid. Cov tshuaj no yog cov nplais muaj txiaj ntsig zoo thiab cov tshuaj tiv thaiv corrosion, siv rau hauv kev kho mob ntawm cov dej ntws thiab cov dej boiler los tiv thaiv cov raj xa dej.

Electroplating additive: Glyoxylic acid. Hauv cov txheej txheem electroplating, glyoxylic acid tuaj yeem txhim kho qhov sib xws thiab gloss ntawm txheej thiab feem ntau siv rau hauv electroplating ntawm cov hlau xws li tooj liab thiab npib tsib xee.

Cov ntaub ntawv Polymer: Glyoxylic acid yog siv los ua tus neeg sawv cev sib txuas hauv kev sib txuas ntawm cov resins thiab txheej txheej, txhim kho huab cua tsis kam thiab ruaj khov ntawm cov ntaub ntawv. Nws tseem tuaj yeem siv los npaj biodegradable polymers (cov ntaub ntawv biodegradable) hauv kev teb rau kev tiv thaiv ib puag ncig.

Lwm yam kev siv niche

Organic synthesis tshawb fawb: Vim yog cov yam ntxwv ntawm cov pab pawg bifunctional, nws feem ntau yog siv los ua cov qauv sib xyaw rau kev kawm txog cov organic tshuaj tiv thaiv mechanisms, xws li kev sim tshuaj xyuas cov tshuaj tiv thaiv condensation thiab cyclization cov tshuaj tiv thaiv.

Khoom noj khoom haus additives: Hauv qee lub tebchaws, lawv cov derivatives (xws li calcium glyalate) tau tso cai siv los ua zaub mov fortifiers ntxiv calcium (yuav ua raws li cov qauv kev nyab xeeb zaub mov).

Hauv kev xaus,glyoxylic acid,nrog nws cov qauv tshwj xeeb thiab kev ua haujlwm zoo, tau dhau los ua "choj" txuas cov tshuaj lom neeg yooj yim thiab cov tshuaj zoo kawg nkaus, ua lub luag haujlwm tsis tuaj yeem ua kom muaj kev noj qab haus huv, kev txhim kho lub neej zoo (tshwj xeeb, khoom siv tawv nqaij), thiab txhawb kev ua liaj ua teb.
