Abstract: Process for the preparation of doped pentasil-type zeolite, which process comprises the steps of: a) preparing an aqueous precursor mixture comprising a silicon source, an aluminum source, doped faujasite seeds, and another type of seeding material, and b) thermally treating the precursor mixture to form a doped pentasil-type zeolite. This process results in doped pentasil-type zeolites in a shorter crystallization time compared to prior art processes.

Abstract: A process for the preparation of alkylene diamine triacetic acid (derivatives) which comprises the conversion of an alkylene diamine (derivative) to a metal salt of an alkylene diamine triacetic acid (derivative). The reaction is carried out in the presence of a polyvalent metal ion Ma+ and the entire reaction is carried out under hydrolyzing conditions if any of the reactants contain or form nitrile or amide groups.

Abstract: A process for imparting flame retardancy to a polyurethane foam comprising the step of incorporating in said polyurethane foam 0.5-50.0 php of at least one flame-retardant phosphate ester is disclosed. Also disclosed is a flame-retardant polyurethane foam composition which comprises a polyurethane foam and 0.5-50.0 php of at least one flame-retardant phosphate ester, as well as the use of a flame-retardant phosphate ester to impart flame retardancy to a polyurethane foam. An example of such a phosphate ester is resorcinol bis(diphenyl phosphate). These flame retardants have the advantage that they reduce fogging caused by evaporation of volatile components from polyurethane foam compositions.
