AKD wax introduction Chemical name: Alkyl Ketene Dimer Alias: AKD wax AKD powder is also called AKD wax. Chemical name is Alkyl ketene dimer. CAS registration number is 144245-85-2. Appearance is pale yellow flake or granular solid. It is produced by fatty acid (C16), via acylation and dehydrochlorination to become AKD wax. AKD wax is mainly used for papermaking neutral sizing agent. R or R' in the above structural formula is the alkyl group, and a series of alkyl ketene dimers can be obtained through modifying different alkyl groups. Octodecane and cetane are applicable to the papermaking neutral sizing agent. Alkyl ketene dimer is a white-to-yellow solid with the melting point of about 47 ~ 51 , which can be soluble in ethyl alcohol, benzene, chloroform and other organic solvents. The reactive group of alkyl ketene dimer-ketone group has high activity and makes esterification reaction with the hydroxyl in cellulose. Product Application AKD wax can be made into AKD emulsion applied as in sizing agent in the papermaking production. AKD wax is emulsified by the cationic emulsifier, and melted AKD wax and emulsifier undergo high-speed shearing and high pressure homogenization to form the liquid AKD sizing agent after cooled. In the papermaking process, application of AKD sizing agent gives the fluid resistance to paper and paperboard to prevent or delay the penetration and diffusion of some liquids on paper fibers, thus satisfying people's requirements on the processing and use of paper products. AKD contains hydrophobic group and hydrophilic group, which are well distributed in the sizing process to transfer to locate the process of bonding with cellulose. AKD emulsion particles stay between negatively charged paper fibers since they carry with positive charge by virtue of cationic starch and PAM and other retention agents; In the pressing and drying process of the paper machine, these globular AKD particles are easily expanded and distributed on the surface of fibers due to the lower melting point to form a homogeneous cover film; When paper is dried and stored for a period, the active group (lactone ring) on AKD molecule makes the esterification reaction with the hydroxyl on fibers under certain conditions to be binding on fibers in the form of fixed covalent bonds. Hydrophobic long-chain alkyls transfer to the paper surface in order to give the penetration resistance to paper.

AKD wax, also known as Alkyl Ketene Dimer wax, is a widely used chemical compound in the paper and packaging industry. It is a synthetic wax that is made from the reaction of fatty acids and ketene, which results in the formation of a complex molecule with unique properties.
Alkyl ketene dimer (AKD) is most common neutral/ alkaline sizing agent. It is an Internal sizing agents. Structurally, it is unsaturated lactones and it is synthesized from fatty acids. Physically it is waxy like milky emulsion chemicals. It has less corrosive to the papermaking machine than acid sizing. For cultural paper and packing paper. CM Chemical has developed the following products. Advantage Alkaline sizing system reduces corrosion of paper machine equipment. Less foam produced by the approach system than the acidic rosin system. AKD pulp sizing cost less than rosin sizing. Hard- sizing can be applied, and the stocking sizing degree is proportional AKD usage. Features Mature production process, easy application, simple adding equipment. High self-retention, good sizing effect, fast curing rate. Strong anti-interference and good stability. Good anti-moisture effect for the paper, can effectively prevent the reduction of RCT.

With the product name "SOFTOMNI 2000" is a proprietary formulated alkaline sizing agent. ALKYL KETENE DIMER (AKD) emulsion, designed to size the paper in the neutral to alkaline ph range of 6.5 to 8.5 SOFTOMNI is a free flowing white emulsion stable to size any type of furnishes preferably containing calcium carbonate. Different type of furnishes require different application method and dosages. SOFTOMNI 2000 is added as such (can be diluted with water to the maximum extent of 1:3 ratio) in the thick stock by diaphragm type of dosing pump. Addition of SOFTOMNI 2000 before filler is preferable to get best sizing effect. The efficiency of ALKYL KETENE DIMER depends on the retention and drainage aid program. The higher the drainage, first pass retention and first pass ash retention, optimum is the efficiency of AKD. A cationic scavenger in necessary where there is high levels of anionic trash in the furnish like deinked pulp.
