Glyoxylic acidndi chinthu chofunikira kwambiri chachilengedwe chokhala ndi magulu a aldehyde ndi carboxyl, ndipo chimagwiritsidwa ntchito kwambiri m'magawo a uinjiniya wa mankhwala, zamankhwala, ndi zonunkhira. Glyoxylic acid CAS 298-12-4 ndi kristalo woyera wokhala ndi fungo lopweteka. Mu mafakitale, nthawi zambiri imapezeka mu mawonekedwe amadzimadzi (madzi opanda mtundu kapena achikasu opepuka). Malo osungunuka a mawonekedwe a anhydrous ndi 98℃, ndipo a hemihydrate ndi 70-75℃.

Munda wa mankhwala: Othandizira pakati

Kukonzekera mankhwala a pakhungu: Glyoxylic acid ili ndi ntchito yolimbikitsa kukonzanso maselo ndikufulumizitsa machiritso a mabala, ndipo imagwiritsidwa ntchito kwambiri mu mafuta opaka kupsa, mankhwala a zilonda zam'kamwa, mankhwala osamalira khungu, ndi zina zotero.

Zopangidwa kuchokera ku amino acid: Glyoxylic acid imagwiritsidwa ntchito popanga zotumphukira za amino acid monga phenylalanine ndi serine, zomwe ndi zofunika kwambiri mu biopharmaceuticals ndi zakudya zowonjezera.

Makampani onunkhira: Mafuta onunkhira opangidwa ndi anthu ambiri

Vanila:Glyoxylic acidndipo guaiacol imadutsa mu condensation, oxidation ndi zina zomwe zimachitika kuti ipange vanillin. Vanillin ndi imodzi mwa zonunkhira zopangidwa zomwe zimagwiritsidwa ntchito kwambiri padziko lonse lapansi ndipo imagwiritsidwa ntchito kuwonjezera kukoma kwa chakudya (makeke, zakumwa), zodzoladzola ndi fodya.

Glyoxylic acid imatha kuchitapo kanthu ndi catechol kuti ipange glyoxylic acid, yomwe ili ndi fungo lokoma komanso lonunkhira bwino ndipo imagwiritsidwa ntchito popangira zonunkhira, sopo ndi maswiti. Ndi gawo lofunikira la fungo la maluwa.

Zokometsera zina: glyoxylic acid ingagwiritsidwenso ntchito kupanga rasiberi ketone (mtundu wa fungo la zipatso), coumarin (mtundu wa fungo la vanila), ndi zina zotero, kuonjezera mitundu ndi kukoma kwa zonunkhira.

Mu gawo la mankhwala ophera tizilombo: Kupanga mankhwala ophera tizilombo ogwira ntchito bwino kwambiri

Mankhwala Ophera Udzu: Glyphosate, yomwe imagwira ntchito popanga glyphosate (mankhwala ophera udzu ambiri), imatha kupha udzu bwino ndipo imagwiritsidwa ntchito kwambiri muulimi, ulimi wa maluwa ndi madera ena.

Mankhwala Ophera Tizilombo: Glyoxylic acid imagwiritsidwa ntchito pokonza quintiaphosphate (mankhwala ophera tizilombo a organophosphorus), omwe ali ndi mphamvu yabwino yolamulira tizilombo towononga mbewu monga mpunga ndi thonje (monga nsabwe za m'masamba), ndipo alibe poizoni wambiri komanso zotsalira.

Mankhwala Ophera Fungicides: Glyoxylic acid imagwiritsidwa ntchito ngati njira yopangira mankhwala enaake ophera fungicides kuti athetse matenda a bowa m'mbewu.

Gawo la uinjiniya wa mankhwala ndi zipangizo

Choyeretsera madzi: Chimayamwa ndi phosphorous acid ndi zinthu zina kuti chipange hydroxyphosphonocarboxylic acid. Mankhwalawa ndi oletsa dzimbiri komanso sikelo yothandiza kwambiri, yomwe imagwiritsidwa ntchito pochiza madzi oyenda m'mafakitale ndi madzi ophikira kuti apewe kukula kwa mapaipi.

Chowonjezera pa electroplating: Glyoxylic acid. Mu ndondomeko ya electroplating, glyoxylic acid imatha kukonza kufanana ndi kunyezimira kwa chophimbacho ndipo nthawi zambiri imagwiritsidwa ntchito popangira zitsulo monga mkuwa ndi nickel.

Zipangizo za polima: Glyoxylic acid imagwiritsidwa ntchito ngati cholumikizira cholumikizira popanga ma resin ndi zokutira, zomwe zimapangitsa kuti zinthuzo zisamavutike komanso kuti zisawonongeke. Ingagwiritsidwenso ntchito kukonzekera ma polima ovunda (zipangizo zovunda) poyankha zofuna zoteteza chilengedwe.

Ntchito zina zapadera

Kafukufuku wa kapangidwe ka zinthu zachilengedwe: Chifukwa cha makhalidwe a magulu awiri ogwira ntchito, nthawi zambiri amagwiritsidwa ntchito ngati chitsanzo cha mankhwala ophunzirira njira zochitira zinthu zachilengedwe, monga kutsimikizira koyesera kwa machitidwe a condensation ndi machitidwe a cyclization.

Zowonjezera pazakudya: M'maiko ena, zinthu zomwe zimachokera ku chakudya (monga calcium glyalate) zimaloledwa kugwiritsidwa ntchito ngati zowonjezera chakudya kuti ziwonjezere calcium (malinga ndi kutsatira malamulo oteteza chakudya).

Pomaliza,asidi wa glyoxylic,Ndi kapangidwe kake kapadera komanso momwe zimagwirira ntchito, zakhala "mlatho" wolumikiza mankhwala oyambira ndi mankhwala apamwamba kwambiri, zomwe zimagwira ntchito yofunika kwambiri pakutsimikizira thanzi lachipatala, kukonza moyo wabwino (zokometsera, zinthu zosamalira khungu), komanso kulimbikitsa ulimi.
