Alkyl ketene dimer (Cat No.:M100585) is a prominent chemical used primarily in the papermaking industry to impart hydrophobic properties to paper. Structurally, it consists of two ketene groups (organic compounds with a carbon-carbon double bond conjugated to a carbon-oxygen double bond) connected by an alkyl chain, typically derived from long-chain fatty acids. When applied to paper, AKD undergoes a reaction with hydroxyl groups on cellulose, forming beta-keto ester linkages that render the paper water-resistant. This reaction not only improves the quality and durability of paper but also contributes to its printability and longevity.
