Glyoxylic acid cas 298-12-4-4

I-Glyoxylic Acid CAS 298-12-4 I-FOWNLOGEDION

Incazelo emfushane:

I-Gyoxxylic acid ayinamibala yokugqwayiza uketshezi oluphuzi ngephunga elibucayi. I-Plyoxylic Acid emsulwa iyi-visuous ketshezi. I-Gyoxxylic acid isetshenziswa kakhulu ezinhlobonhlobo zamakhemikhali kanye ne-organic Chemical realent.

I-Glycolic acid incane kakhulu emanzini ngenxa yemvelo yayo ye-polar namaqembu e-carboxylic acid acid. Kuyancibilika futhi ezinhlobonhlobo zezinto eziphilayo ezifana ne-ethanol ne-acetone.

Isicelo

Embonini yekhalo, kusetshenziswa njengento eluhlaza yokukhiqizwa kwe-methyl vanillin ne-ethyl vanillin.

Isetshenziswa embonini yezemithi njengomuthi we-antihypensite, i-DP-Hydroxypeyyllycine (i-Antihleally Sportmucethical Intermediate), i-Acetropheum Antibiotic Amoxicillin (Oral), i-Acetophenone, i-Amino acid nezinye izikhala zokwenziwa komphakathi.

Kusetshenziswe njenge-Intermediate yezinto zokwenziwa kwezindwangu ezi-varnish, amadasi, amapulasitiki namakhemikhali ezolimo.

Ingasetshenziswa futhi ukukhiqiza i-allantoin. I-Allantoin ingumgadli wezidakamizwa zokulwa namakhambi, imikhiqizo yemithi, kanye namakhemikhali nsuku zonke.

2. Isicelo se-Biochemical: I-Glyoxylic Acid ibamba iqhaza ezinqubweni ze-biochemical futhi ingasetshenziswa ukutadisha izindlela ze-metabolic.

I-3. Imboni yendwangu: Isetshenziswa njenge-mordwant ekukhiqizeni udayi kanye nokucutshungulwa kwezindwangu.

4. Izimonyo: I-Glycolic acid kwesinye isikhathi isetshenziswa kumafomethi wezimonyo, ikakhulukazi emikhiqizweni yokuqondisa izinwele, ngenxa yekhono layo lokuguqula iKeratin.

I-5. I-Chemistry ehlaziya: Ingasetshenziswa njenge-reagent ngezindlela ezahlukahlukene zokuhlaziya, kufaka phakathi ukuzimisela kwama-amino acid athile nezinye izinhlanganisela.

6. Ukukhiqizwa kwe-polymer: I-Gyoxxylic Acid ingasetshenziswa ukukhiqiza ama-polymers athile nama-resins.

Ukubeka

Gcina uvalwe ngokuqinile, gcina kude nelanga, gwema ukuxhumana nomoya, futhi ugcine endaweni epholile, eyomile futhi enomoya. Gcina futhi uhambise ngokuhambisana nemigomo yamakhemikhali anobuthi.

1. Isitsha: Sebenzisa iziqukathi ze-airtight ezenziwe ngezinto ezihambisanayo, njengengilazi noma amapulasitiki athile, ukuvikela ukungcoliswa nokuhwamuka.

2. Ukushisa: gcina endaweni epholile, eyomile kude nokukhanya kwelanga okuqondile nokushisa. Ngokufanelekile, gcina amazinga okushisa angaphansi kuka-25 ° C (77 ° F).

3. Ukuphefumula umoya: qiniseka ukuthi indawo yokugcina inomoya omuhle ukugwema ukunqwabelana kwe-vapor.

4. Ukungalingani: I-Gyoxxylic Acid kufanele igcinwe kude nama-oxidants aqinile, izisekelo kanye nezinye izinto ezisebenzayo ukuvikela ukusabela okuyingozi.

I-5. Ilebula: Faka ilebula ngokucacile iziqukathi ngegama lamakhemikhali, okuhlushwa, kanye nemininingwane yengozi.

Izakhiwo Zomzimba Nezamakhemikhali

Lo mkhiqizo uluketshezi oluphuzi olungenamibala noma olukhanyayo. Akunangqondo ngamanzi, ancibilika kancane e-ethanol naku-ether. Insoluble kuma-esters kanye nama-solivents amnandi. Isixazululo sizinzile kakhulu futhi asiwonakali lapho sibekwe emoyeni, futhi i-glyoxylic acid ikhona ngefomu elinamanzi esikhangisweni samanzi. Iyakhuthaza.

Izisombululo ngesikhathi sokuhamba

Lapho uhambisa i-Glycolic acid, kufanele kuthathwe izinyathelo ezimbalwa zokuqinisekisa ukuphepha nokulandela imithetho. Nayi eminye imininingwane ebalulekile okufanele uyinake:

1. Ukupakisha: Sebenzisa iziqukathi ezilungele i-glyoxylic acid, njengengilazi noma amapulasitiki athile. Qiniseka ukuthi isitsha sivalwe ngokuqinile ukuvikela ukuvuza nokuhwamuka.

2. Ilebula: Faka ilebula ngokucacile zonke iziqukathi ngegama lamakhemikhali, uphawu lwengozi kanye nanoma yiluphi ulwazi lokuphepha olufanele. Lokhu kubandakanya okukhombisa ukuthi kuyinto eyingozi futhi enobungozi.

I-3. Imishini yokuzivikela (i-PPE): Qinisekisa ukuthi abasebenzi ababandakanyeka kwezokuhamba begqoke i-PPE efanelekile, kufaka phakathi amagilavu, ama-goggles kanye nezingubo zokuvikela ukunciphisa ukubonakaliswa.

4. Ukulawulwa kokushisa: Uma kunesidingo, ukuthutha i-glyoxylic acid endaweni elawulwa ukushisa lokushisa lokugwema amazinga okushisa aphezulu angathinta ukuqina kwawo.

I-6. Izinqubo eziphuthumayo: Uma kwenzeka kuchitheka noma ukuvuza ngesikhathi sokuhamba, ukuthuthukisa izinqubo eziphuthumayo. Lokhu kufaka phakathi ukuchitha ama-kits kanye nezinto zosizo lokuqala zilungele.

7. Ukulandela umthetho wokulawula: Qinisekisa ukuhambisana nemithetho yasekhaya, kazwelonke, neyesizwe maqondana nokuhamba kwezinto eziyingozi. Lokhu kungafaka ukuthola izimvume ezidingekayo nokulandela imihlahlandlela ethile yokuthumela.

8. Ukuqeqeshwa: Qinisekisa ukuthi bonke abasebenzi ababandakanyeka ezokuthutha ze-GyoxyLlic Acid baqeqeshelwe ekuphatheni izimpahla eziyingozi futhi bayazi ubungozi obuhambisana ne-glyoxylic acid.
