High functionality Methylene Diphenyl Diisocyanate (HFMDI) 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 […]

Adipic Acid
CAS: 124-04-9
Adipic Acid also known as Hexane-1,6-dioic acid is a dibasic acid with the molecular formula C3H8O4, CAS 124-04-9. Adipic acid is slightly soluble in water and soluble in alcohol and acetone.
Adipic Acid Chemical Structure Composition.
Production
Adipic acid is white, crystalline compound mainly obtained by oxidation of cyclohexanol and cyclohexanone with nitric acid.
An alternative method of production of adipic acid is the hydrocarbonylation of butadiene, oxidation cleavage of cyclohexene.
Uses
More than 92% of the production of adipic acid is dedicated for the production of nylon 6,6 by a reaction with HMD Hexamethylene diamine.
Nylon is utilized in fibbers, clothing, plastics, filaments, food packaging, …
Adipic acid is also used in polyurethane resins, foam, shoe soles, and as food additive.
Esters of adipic Acid are used as plasticizers for PVC (Polyvinyl Chloride) resins and lubricant component.
Arpadis is one of the largest chemical distributor in Europe.
Arpadis is handling the storage, transport, export & import formalities of Adipic Acid globally.
