Methylene Diphenyl Diisocyanate (MDI) CAS:9016-87-9 Methylene Diphenyl Diisocyanate is produced by a 4 steps reaction based on benzene as feedstock. There are 3 isomers of MDI : 2,2-MDI, 2,4-MDI, and 4,4-MDI. The 4,4 isomer is known as pure or monomeric MDI (mMDI).The Polymeric MDI so called Crude MDI contains monomeric MDI and products with higher […]

DoDecaneDioic Acid (DDDA)
Dodecanedioic acid (DDDA) is a dibasic acid. It’s a white flakes solid with a molecular formula C12H22O4.
Dodecanedioic Acid Chemical Structure Composition.
There are two different routes to produce DDDA: synthetic production and biological production.
Traditionally, DDDA is produced from butadiene using a chemical process. The butadiene is converted into cyclododecatriene through a cyclotrimerization process. The cyclododecatriene is then converted into dodecanedioic acid. Feedstock is methanol
A newer approach is biological production. Using biotechnology, DDDA is created from Paraffin wax with yeast (Candida Tropicalis). This way has made DDDA a cost-effective compound.
Dodecanedioic Acid is mainly used in top-grade powder coatings and paint, adhesives, pulp & paper, chemical and industrial facilities, surfactants, antiseptics.
In combination with Amine, DDDA is used to produce engineering plastics polyamide resins wich is a high performance nylon 6-12, adhesives, diester synthetic lubricants, fibers, curatives, plasticizers, polyester coatings, epoxy resins.
When used in a mixture with other dibasic acids DDDA is especially effective as a ferrous corrosion inhibitor for metalworking fluids, engine coolants, metal cleaners, aqueous hydraulic fluids. DDDA can also be used as a complexing agent for lithium complex grease which will increase dropping point and improve mechanical stability.
