Particle size determination of urea-paraffin adducts by microphotography

  • Published:
Chemistry and Technology of Fuels and Oils Aims and scope

Summary

  1. 1.

    The urea-paraffin adduct is a finely dispersed material, which consists mainly of particles with a diameter of 20–200μ, the particles below 60μ representing about 55–60%.

  2. 2.

    After passage of the adduct through the centrifuge an increase in particle size is noticed, due to conglomeration of very fine particles.
