摘要:
AbstractThe lubricating properties of the synthetic lubricating oil prepared as described in the first communication were tested in a standard engine under very drastic conditions (ring sticking test). The lubricating properties of the oil in general were very good.The cetane number of the middle oil obtained by polymerization of ethene was 32.The use of a liquid diluent in the catalytic polymerization of ethene is not essential.Besides nickel or nickel alloys, other compounds such especially as cobalt and also aluminium, and to a certain extent also dry hydrochloric acid can exercise a favourable influence on the polymerization of ethene with aluminium chloride.

摘要:
AbstractIn the preparation of indoles substituted in the pyrrole nucleus starting from α‐arylaminoketones, two types of indoles may be obtained according as they are formed by ring closure or by rearrangement. The dipole moment of a number of indoles whose constitution had been definitely determined by other methods was measured. It was found that in some cases it is possible to distinguish between the two ways of indole formation by means of the dipole mome
