Arkema diacetone alcohol or DAA is an oxygenated solvent derived from acetone which has two alcohol and ketone functions. It has a high purity. It is colourless and odourless and has a low evaporation rate.

Diacetone alcohol is mainly used in paints and coatings (coil coatings, wood varnishes, architectural coatings…). It is a good solvent for organic peroxides and can also be used for the treatment of textiles and leather, in chemical synthesis, or as a cleaning solvent.

The Dianol^® range contains polyether polyols which provide improved adhesion and resistance to high temperatures and hydrolysis. The Dianol^® polyols are mainly used as building blocks in polyurethane, polyester and epoxy resins. They are also used as reactive diluents in industrial paints. The main applications for the Dianol^® polyols are paints, coatings, inks, composites and adhesives.

The Dinoram^® surfactants are cationic rapid setting (CRS) emulsifiers for bitumen.

It reduces the physical and chemical interactions of the fines with the air bubbles during the flotation.
It contributes to the elimination of the inks with the flotation sludges.
Added to the pulper with the other deinking chemicals, Dipflo™ helps to increase both the deinking yield and the deinked pulp brightness.

DMDO (1,8-Dimercapto-3,6-dioxaoctane) is a di-functional mercaptan compound commonly used in the manufacturing of epoxy glues or sulfurized polymers in adhesives fields.

Dimethyl Disulfide, DMDS Evolution® E2 is the most efficient and safe sulfur provider for Hydrotreatment catalyst activation and steamcrackers cocking prevention. Our experienced technical support team is available to share its knowledge on DMDS Evolution® E2 and our Research and development team in Groupement de recherche de Lacq keeps developing programs to ease and improve its use and performances. Arkema’s world class production sites and global logistic network enable a local, easy and reliable sourcing; and our Carelflex® teams are available locally to perform your catalyst sulfiding. Our operations meet the highest certification for a consistent product quality and a service that meets our customers stringent standards. 

Ethylene is the largest volume of basic chemical produced by the steamcracking of hydrocarbons. Cracking to produce olefins, suffers from side reactions that product carbon monoxide (CO) and carbon deposits on the cracking coils. Excess of CO leads to off spec ethylene and while fast coking reduces cracking furnace run lengths, productivity and profitability. Fortunately, a very low concentration of DMDS Evolution® E2 injected in the cracking furnace mitigates those side reactions. DMDS Evolution® E2 decomposes in the cracking tube only into H2S and methane without solid or coke deposit. By modifying the surface composition of the cracking tube, H2S poisons the metal sites involved in the formation of CO and coke. Year after year, all licensors of ethylene furnaces and olefins manufacturers recommend injecting DMDS Evolution® E2 to meet the designed performance. 

Dimethyl disulfide, DMDS Evolution® E2, only available from Arkema, is a breakthrough formulation for a better user experience on-site, providing a pleasant fragrance. It is successfully adopted as the standard sulfiding and anticoking agent of choice at refineries, renewable diesel plants, Propane and Butane dehydrogenation units (PDH, BDH) and steamcrackers.
