Staff-Industry Collaborative Report p-XYLENE FROM PETROLEUM

Solubility Data for p-Xylene.

“…Table I gives mole per cent composition data on the feed stock mixture used in this work. Amounts of the four principal constituents (ethylbenzene and the three xylene isomers) are similar to those present in typical feed stock mixtures reported previously (2).…”

Crystallization

“…Haines, Powers, and Bennett (38) have published a staffindustry collaborative report on the crystallization aspects of p-xylene production. Coats (20) has patented a process for the separation of p-xylene by crystallization in which heavy depositions of p-xylene on the cooling coils are prevented by making the coils a part of a high-amperage circuit and heating it periodically.…”
