FAQ - Technical & Supply Chain
-
Q:
What is Cyclohexylamine used for?
A: Cyclohexylamine (CHA), CAS 108-91-8, is a primary amine used mainly as an intermediate for rubber chemicals, corrosion inhibitors, boiler-water treatment agents, sweetener synthesis and other organic syntheses. It is also a building block for cyclohexanol, cyclohexanone and caprolactam. The intended downstream reaction should be stated because impurity sensitivity varies by process. -
Q:
Why is Cyclohexylamine important for rubber and sweetener synthesis?
A: Cyclohexylamine is a key precursor for the sulfenamide rubber accelerator N-cyclohexyl-2-benzothiazole sulfonamide, commonly called CBS, and for sodium cyclamate. These routes can be sensitive to related amines and oxidation products, so suitable purity and controlled impurities are important. -
Q:
Which specification parameters should be compared for Cyclohexylamine?
A: Compare GC assay, color and appearance, water, and limits for cyclohexanol, cyclohexanone, dicyclohexylamine or other related amines. The analytical method and acceptance limits should be fixed so offers can be evaluated on the same basis. -
Q:
What are typical physical properties of Cyclohexylamine?
A: Cyclohexylamine is normally a colorless to pale-yellow liquid with an amine odor. Typical values are a boiling point around 134 C, melting point near -17 C, density about 0.865-0.867 g/mL, and a closed-cup flash point near 27 C. -
Q:
How should Cyclohexylamine be stored and transported?
A: Cyclohexylamine is commonly assigned UN 2357, Hazard Class 8 with a flammable-liquid subsidiary risk, Packing Group II. Store it in a cool, well-ventilated area away from heat, sparks, oxidizers, acids, food and feed, and keep containers closed.
