1.Introduction of Dicyclohexylcarbodiimide

Dicyclohexylcarbodiimide,with its CAS NO.538-75-0,is a kind of white or slight yellow crystalline solid. It has synonyms of 1,3-Dicyclohexylcarbodiimide ; Bis(cyclohexyl)carbodiimide ; Carbodicyclohexylimide ; DCC ; DCCD ; DCCI ; N,N'-Dicyclohexylcarbodiimide ; N,N'-Methanetetraylbiscyclohexaamine and NSC 30022. Dicyclohexylcarbodiimide is an imide. Amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P₂O₅ or SOCl₂ generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NO_x). Dicyclohexylcarbodiimide is incompatible with acids and oxidizing agents. It is probably combustible.

5.Production of Dicyclohexylcarbodiimide

Dicyclohexylcarbodiimide has several synthesis methods. Pri-Bara et al. use palladium acetate, iodine, and oxygen to couple cyclohexyl amine and cyclohexyl isocyanide.
C₆H₁₁NC + C₆H₁₁NH₂ + O₂ → (C₆H₁₁N)₂C + H₂O
Tang et al. condense two isocyanates using the catalyst OP(MeNCH₂CH₂)₃N in yields of 92%:

Dicyclohexylcarbodiimide has also been made from dicyclohexylurea using a phase transfer catalyst by Jaszay et al. The disubstituted urea, arenesulfonyl chloride, and potassium carbonate react in toluene in the presence of benzyl trimethylammonium chloride to give Dicyclohexylcarbodiimide in 50% yield.
