Propanedioic Acid | 141-82-2
Inkcazo yeMveliso:
| Into | Propanedioic acid |
| Umxholo(%)≥ | 99 |
Ingcaciso yeMveliso:
I-Malonic acid, eyaziwa ngokuba yi-malonic acid, i-asidi ephilayo ene-chemical formula HOOCCH2COOH, enyibilikayo emanzini, i-alcohol, i-ethers, i-acetone kunye ne-pyridine, kwaye ikhona njengetyuwa ye-calcium kwiingcambu ze-beet zeswekile. I-asidi ye-Malonic yikristale engenambala engenambala, i-melting point 135.6 ° C, ibolile kwi-140 ° C, ubuninzi be-1.619g / cm3 (16 ° C).
Isicelo:
(1) Ikakhulu isetyenziswa njengama-pharmaceutical intermediates, ikwasetyenziswa kwiziqholo, izincamathelisi, izongezo ze-resin, i-electroplating kunye ne-polish agents, njl.
(2) Isetyenziswe njenge-agent eyinkimbinkimbi, iphinda isetyenziswe ekulungiseleleni ityuwa ye-barbiturate, njl.
3
(4) I-Malonic acid kunye ne-esters yayo isetyenziswa kakhulu kwiziqhumiso, i-adhesives, i-resin additives, i-pharmaceutical intermediates, i-electroplating kunye ne-polish agents, ii-agent zokulawula ukuqhuma, i-welding flux additives eshushu, njl. , i-barbiturates, i-vitamin B1, i-vitamin B2, i-vitamin B6, i-phenyl pausticum, i-amino acids, njl njl. I-Malonic acid isetyenziswe njenge-agent yonyango ye-aluminiyam kwaye ayinayo ingxaki yongcoliseko njengoko kuphela kwamanzi kunye ne-carbon dioxide ziveliswa xa ishushu kwaye ibola. . Kule meko, inenzuzo enkulu ngaphezu kwee-agent zonyango ezisekelwe kwi-asidi ezifana ne-asidi ye-formic, eyayisetyenziswa kwixesha elidlulileyo.
(5) I-Malonic acid isetyenziselwa ukongeza kwi-chemical plating kunye ne-agent ye-polish ye-electroplating.
