Aside ya Glyoxylic CAS 298-12-4
Aside Glyoxylic CAS no 298-12-4, izwi kandi nka aside formoic, aside glyoxylic yuzuye amazi na aside oxyacetic, formula ya chemical C2H203, ni aside aldehyde yoroshye cyane, iboneka mu mbuto zitarakura, mu mababi y’icyatsi kibisi na beterave. Amabuye aturuka mu mazi ni kristu imwe (irimo 1/2 cy'amazi ya kristu). Uburemere bwa molekile ni 70.04. Aho ishongesha ni 98 ℃. Aside Glyoxylic ifite uburyohe butari bwiza. Aside Glyoxylic ni aside ikomeye yangiza, yoroshye kuyihinduramo kandi ishobora gukora umusemburo iyo ishyizwe mu kirere. Aside Glyoxylic ishonga gato muri ethanol, ether na benzene, kandi ishobora gushonga mu mazi. Umuti w’amazi urahamye kandi ntugabanuka mu kirere. Umuti w’aside Glyoxylic uba mu muti w’amazi mu buryo bw’amazi. Aside Glyoxylic ishobora gukorana n’ibyuma byinshi usibye icyuma kitagira umugese. Umuti w’aside Glyoxylic ufite imiterere ya aside na aldehyde.
Aside ya Glyoxylic (CAS 298-12-4) ntabwo ifite igipimo cy’ubuziranenge kidahinduka kandi gihuriweho. Ubuziranenge bwayo bugomba gushyirwa mu byiciro hakurikijwe imiterere yihariye (igisubizo cy’ikirahure cyangwa amazi) n’imiterere y’ikoreshwa. Dushobora gutanga ibisobanuro bibiri by’ingenzi:aside glyoxylic 98% iminota(ikirahure) naaside glyoxylic 50%(umuti w'amazi).

1. Aside Glyoxylic CAS 298-12-4 ikoreshwa nk'ibikoresho bya methyl vanillin, ethyl vanillin mu nganda zikoresha uburyohe.
2. Aside Glyoxylic CAS 298-12-4 ikoreshwa nk'interuro ya D-hydroxybenzeneglycine, antibiyotike ya broadspectrum, ,acetophenone, aside amino n'ibindi.
3. Aside Glyoxylic CAS 298-12-4 ikoreshwa mu bikoresho bya varnish, amarangi, pulasitiki, agrochemical, allantoin n'ibindi. Aside Glyoxylic ikunzwe cyane mu nganda z'ubwiza, aside glyoxylic ikoreshwa mu irangi ry'umusatsi; ibicuruzwa byo kwita ku musatsi; ibikoresho byo kwita ku ruhu n'ibindi, ariko aside glyoxylic mu bikoresho byo mu musatsi ikora neza cyane.
4. Aside ya Glyoxylic ni ibikoresho bikoreshwa mu gusukura amazi, imiti yica udukoko. Aside ya Glyoxylic ikoreshwa nk'igice cy'ibikoresho bya varnish n'irangi.
5. Aside ya Glyoxylic CAS 298-12-4 ishobora kandi gukoreshwa mu kubungabunga ibiryo, nk'ikintu gihuza polimeri ndetse no nk'inyongeramusaruro.
1. Dukora umuti wa aside glyoxylic ufite ubuziranenge bwa 50% by'iminota n'ubuziranenge bwa 98%. Abakiriya bashobora guhitamo bitewe n'ibyo bakeneye n'uburyo bakora.
Niba umukiriya afite ibisabwa kugira ngo umuti wa aside glyoxylic ube mwiza, dushobora kandi guhindura uburyo butandukanye bwo gusukura umukiriya, nko mu minota 40%.
2. Umubare w'ibara ry'amazi ya aside glyoxylic ushobora kugenzurwa. Hakurikijwe ibyo abakiriya bakeneye bitandukanye (inyongeramusaruro zo kwisiga, formula zo kugorora umusatsi, ibice bihumura neza, nibindi), umubare w'ibara ushobora gutoranywa uri munsi ya 50, munsi ya 100, na munsi ya 300
3. Umuti wa aside glyoxylic n'umuti ukomeye ntabwo birimo glyoxal. Abakiriya benshi bo kugorora umusatsi no kwita ku musatsi bakeneye cyane cyane iyi spec. Kubera ko Glyoxal ifatwa nk'umwanda, kuyibonekamo bishobora kugira ingaruka zikomeye ku bwiza bw'umuti n'ibara ry'umuti. Ibicuruzwa bya aside glyoxylic CAS 298 12 4 byashimwe cyane n'abakiriya.
4. guhindura ibintu uko ubyifuza:
Gupfunyika ibicuruzwa bishobora guhindurwa hakurikijwe ibyo abakiriya bakeneye-25kg/ingoma, 50kg/ingoma, 250kg/ingoma, 1250kg/ingoma ya IBC, ISO TANK...
ibirango: Hindura ibirango ku giti cyawe ku bakiriya
5. Dufite abakora ingendo z'imizigo b'inararibonye bashobora kukugezaho aside Glyoxylic ku gihe kandi mu mutekano. Dufite abakiriya mu turere twinshi nko mu turere twa Amerika y'Epfo nka Brezili, Uburasirazuba bwo Hagati, na Aziya y'Amajyepfo y'Uburasirazuba.
25kgs/ingoma n'ingoma ya IBC ya 1250kgs na 25ton/30ISO TANKIngoma ya pulasitiki, ibiro 25.
Kubika: Bibikwa mu bubiko bwumye kandi bufite umwuka mwiza, birinda izuba ryinshi, birundanye gato hanyuma bigashyirwa hasi.
Nimero ya CAS 298-12-4 Abatanga aside ya Glyoxylic. Dushobora gutanga igiciro cya aside ya glyoxylic ku giciro gito.
