CPhysical and Chemical properties: Pale yellow water solution liquid. Like other dialdehydes (e.g. glyoxal), glutaraldehyde does not exist typically as the dialdehyde but as the hydrate. Monomeric glutaraldehyde can polymerize by aldol condensation reaction yielding alpha, beta-unsaturated poly-glutaraldehyde. This reaction usually occurs at alkaline pH values.PreparationGlutaraldehyde is produced industrially by the oxidation of cyclopentene and by the Diels-Alder reaction of acrolein and methyl vinyl ether followed by hydrolysis.ApplicationGlutaraldehyde is used as biocides and leather tanning agent.Specification*ItemsSpecificationglutaraldehyde content25%min., 50.0% min.color100 Hazen unit max.pH value3.0-5.0AppearancePale yellow transparent liquidStandard Packaging125, 220 kgs/poly drum; 1100kgs/IBCRisks and Safety InformationCORROSIVE LIQUID, ACIDIC, N.O.S.UN 3265Class: 8PG IIIR-Phrase: 23/25 34 42/43 50S-Phrase: 1/2 26 36/37/39 45 61
