The reversibility of the reaction CaCO3 ⇄ CaO+CO2
Tập 23 Số 10 - Trang 733-742 - 1973
AbstractThe 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 surface area on going from the non‐porous calcium carbonate to the
oxide an...
Synthesis and photochemical stability of 1‐phenylazo‐2‐naphthol dyes containing insulated singlet oxygen quenching groups
Tập 27 Số 4 - Trang 558-564 - 1977
AbstractAlthough 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 dialkylaminomethyl‐groups
towards hydrogen...
The preparation and characterisation of crystalline α‐zirconium phosphate
Tập 23 Số 3 - Trang 215-224 - 1973
AbstractCrystalline 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.
Kinetics of benzene hydrogenation by supported nickel at low temperature

Continuous production of high‐purity water by electro‐deionisation
Tập 21 Số 4 - Trang 117-120 - 1971
AbstractOperating 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 were used. It was shown that strongly acidic cation‐exchange resin plus
strong...
Hydrolysis of pentosans in bagasse pith
Tập 26 Số 5 - Trang 283-287 - 1976
AbstractWork 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 concentration less than 2% by
weight an...
