Abstract

Tetrahydrodicyclopentadienylene diamine is prepared by reacting dicyclopentadiene with hydrocyanic acid and sulphuric acid in two stages, the first stage being carried out at - 5 DEG to + 20 DEG C. using 1 to 3 moles of sulphuric acid, while the second stage is carried out at a temperature of 0 DEG to 30 DEG C., such an amount of sulphuric acid being added that the total amount of sulphuric acid used is from 3 to 6 moles per mole of dicyclopentadiene, but at least one mole more than in the first stage, the reaction mixture then being hydrolysed and the diamine product being recovered by conventional methods. The whole of the hydrocyanic acid may be present in the first stage. Both the temperature and the strength of the sulphuric acid in the first stage are preferably lower than those in the second stage.
