Safe Transport of Acrylic Acid in Railroad Tank Cars. Part 1: Determination of the Self-Accelerating Decomposition Temperature.

Experiments according to a test specified in the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, and numerical simulations by means of a finite element method are employed to determine the self-accelerating decomposition temperature of acrylic acid in a railroad tank car. The results demonstrate that the transport of acrylic acid in big tank cars is safe as long as some basic conditions are taken into account. [ABSTRACT FROM AUTHOR]
