Fibre Chemistry Aims and scope

Conclusions

Experimental data are given which indicate that the cationic initiation of caprolactam, which is initiated by acid esters of H3PO4 with lower alcohols, is analogous to the reaction in the presence of hydrogen halide acids, and not to that in the presence of acidic polyethylene glycol phosphates.

The catalytic activity of the low-molecular-weight phosphates decreases with increase in the size of the alcoholic radical.
