The chloro, nitrato and sulphato complexes of cobalt, nickel and copper with octadecylamine have been prepared. In the cobalt complexes, the cobalt atoms are in a tetrahedral environment while in the nickel and copper complexes the metal atoms are in octahedral environments. The initial decomposition temperatures of the complexes have been studied by thermogravimetry. The performance properties of the complexes as pigments for poly(vinyl chloride) have been investigated. The weather resistance, light fastness, migration resistance and heat stability have been considered.

The chloro compounds of 4-(butylamino) benzoic acid with cobalt, nickel and copper were prepared in an ethanolic solution from which solid compounds were isolated. The compounds were characterised with analyses, magnetic moments, vibrational and electronic spectra. The cobalt compound has a tetrahedral structure while the nickel and copper compounds have polymeric octahedral structures. The thermal behaviour of these compounds has been studied by thermogravimetry and differential thermal analysis. The cobalt compound, which is hydrated, loses water of crystallisation followed by loss of organic ligand and chlorine to give the metal oxide. The nickel and copper compounds lose organic ligand and chlorine to give the metal oxide.

Complexes of triethylenediamine, 4-(butylamino)benzoic acid and triethylenediamine with the chlorides of cobalt(II), nickel(II) and copper(II) have been prepared. The stereochemistry for each of the complexes has been obtained from spectral and magnetic data. The decomposition of the complexes has been studied by thermogravimetry. The performance properties of the complexes as colouring materials for poly(vinyl chloride) has been investigated by studying weather resistance, lightfastness, acid and alkali resistance, migration resistance, tensile strength and heat stability.

Complexes of 4-(2-aminoethyl) pyridine, p-phenetidine and N,N′-dimethylethanolamine with the chlorides of cobalt(II), nickel(II) and copper(II) have been prepared. The stereochemistry for each of the complexes has been obtained from spectral and magnetic data. The decompositions of the complexes have been studied by thermogravimetry. The performance properties of the complexes as coloring materials for poly(vinyl chloride) have been investigated by studying weather resistance, light fastness, acid and alkali resistance, migration resistance, tensile strength and heat stability.

Compounds of triethylenediamine with the chlorides of manganese, iron, cobalt, nickel and copper have been prepared in ethanolic solution. The compounds, which have been characterised by analyses, magnetic moments, and vibrational and electronic spectra, show that for the iron and cobalt compounds the metal ions are in a tetrahedral environment, whereas for the manganese, nickel and copper compounds the metal ions are in an octahedral environment. The thermal behaviour of these compounds has been studied by thermogravimetry and differential thermal analysis. The iron, cobalt, nickel and copper compounds which are hydrated lose water, followed by organic ligand and halogen, to give the metal oxide. The manganese compound loses the organic ligand and halogen to form an oxide of manganese.

The chloro compounds of p-phenetidine with cobalt(II), nickel(II) and copper(II) were prepared in ethanolic solution from which solid compounds were isolated. The suggested structure for the cobalt compound is tetrahedral, while for the nickel and copper it is octahedral. The techniques of thermogravimetry and differential thermal analysis show that the compounds dichloro-bis(p-phenetidine) cobalt(II) and dichloro-bis(p-phenetidine) nickel(II) form intermediate compounds before the metal oxide is produced. The compound dichloro-bis(p-phenetidine) copper(II) decomposes with loss of the phenetidine and chlorine and the formation of copper oxide.

A general technique for predicting properties of highly turbulent, chemically reacting diffusion flames with regions of recirculating flow and with radial pressure gradients is described. The technique is explicitly written for calculations on low altitude, axisymmetric rocket exhaust flames, but may readily be applied to other combustion systems where coupling between chemical reactions and turbulent mixing processes is strong. The application of the method is illustrated: agreement between results obtained and experimental measurements is good, although more stringent further testing is needed.

A general technique for predicting a wide variety of properties of a highly turbulent, chemically reacting, low-altitude rocket exhaust flame is described, and its application illustrated. The agreement between theory and experiment which it provides is generally good. The limitations of the technique are indicated and suggestions for further work designed to improve its accuracy are made.
