Abstract
Data are presented showing the effect of degree of refining upon the specific gravity, viscosity, unsulphonatable mineral residue (U.R.), refractive index, average molecular weight, group analysis, sulphur content and phototoxicity of two spindle oil distillates in the boiling range 300–390° C. Cucumber plants proved very suitable for demonstrating differences in phyto‐toxic properties of the oils. Spindle oils refined to a U.R. of 82 or higher, and a specific gravity of 0.885 or lower, showed no phytotoxicity in the tests on these plants. A fair agreement was found between the results of these tests and the specifications laid down by Dr H. Martin for spray oils.
