Four grams of SBP and a predetermined amount of concen- trated sulphuric acid (96%, by weight) were mixed in a glass reactor. Initially, an immediate reaction and an intensive gas evolving were occurred in a few minutes. During this period, ...
sulphuric acid. The reaction with urea-sulphuric acid may be carried out at ordinary or even slightly elevated temperatures (30-40° C.) without the production of inferior products. The concentration of the modifying agent depends on several factors, chiefly the agent being used and the material...
