The reversibility of the reaction CaCO3 ⇄ CaO+CO2Abstract The reversibility of the reaction CaCO3 ⇌ CaO+CO2 has been examined through a large number of cycles (up to 40), mainly at 866 °C. The decomposition to the oxide is always 100% but the reactivity of the oxide so formed to carbon dioxide falls off markedly after a rapid initial reaction. There is a large increase in ... ...

Synthesis and photochemical stability of 1‐phenylazo‐2‐naphthol dyes containing insulated singlet oxygen quenching groupsAbstract Although 1‐arylazo‐2‐naphthols undergo direct and sensitised photochemical fading in solution by a singlet oxygen mechanism, the introduction of singlet oxygen‐quenching substituents (N,N‐dialkylaminomethyl‐) affords no protection against fading, and in many cases accelerates photodegradation. This has been attributed to the high reactivity of the dialkylam... ...

The preparation and characterisation of crystalline α‐zirconium phosphateAbstract Crystalline α‐zirconium phosphate has been prepared by four methods. The products have been characterised by chemical and thermal analysis, X‐ray and infrared spectroscopy, surface area, porosity and particle size determinations and electron microscopy. A method is recommended for the preparation of crystalline α‐zirconium phosphate.

Continuous production of high‐purity water by electro‐deionisationAbstract Operating conditions were investigated for a packed‐bed membrane cell for electro‐deionisation of brackish or tap water to give high‐purity water with electrical conductivity of the order 0.1 μmho/cm. Flow rates of 10–40 h−1 , current densities of 0.5–5 mA/cm2 , and incoming solution concentrations of up to 0.01 N wer... ...

Hydrolysis of pentosans in bagasse pithAbstract Work has been conducted on the hydrolysis of pentosans in bagasse pith as the first part of a study of the chemistry of bagasse processing aimed at establishing an integrated industry. Bagasse pith is the fine part screened out and discarded as waste during the preparation of raw material for bagasse pulping plant. By using dilute sulphuric acid at a concen... ...
