Title: Improvements in and relating to the treatment of paraffinic tar oils
Filed: 1944-08-29
Abstract: Paraffinic tar oils direct from a tar still, boiling between 150 DEG and 250 DEG  C., are fractionated and separated into short-range fractions boiling within a range of 20 DEG  C., these fractions are freed from tar acids and, optionally, tar bases and fractionated separately.  This process enables the tar oils to be separated into products which are relatively rich in paraffin hydrocarbons and others which are relatively rich in aromatic hydrocarbons. The early distillate in each of the secondary fractionations consists mainly of aromatic compounds, while the portion distilling later and the residue are rich in paraffins, and may be used as Diesel fuel.  In an example, a heavy naphtha of boiling range 171 DEG  to 212 DEG  C. from a continuous tar still was separated by fractionation into 5 DEG C. fractions from 150 DEG  C. onwards.  The 185 DEG -190 DEG  C. fraction, after being freed from tar acids and tar bases, had a boiling range of 192 DEG  to 212 DEG  C.  This neutral oil was fractionated and separated into four equal fractions: the first fraction, of end-point 193 DEG  C., had a specific gravity of 0.92; while the residues, remaining after the temperature reached 209 DEG C., had a specific gravity of 0.79 and contained 87 per cent. paraffins.

Abstract: 312,919. Boehringer, A., (trading as Boehringer Sohn, C. H.). June 1, 1928, [Convention date]. Samples furnished. Pyridine and piperidine alcohols.-Pyridine compounds containing a CH2.CO.R group (R represents hydrogen, alkyl, aralkyl or aryl) in the 2-position or in both 2-and 6-positions are treated with hydrogen in the presence of a hydrogenating catalyst, such as nickel or metals of the platinum group, whereby the carbonyl group or groups is or are reduced to the carbinol stage and then the pyridine nucleus becomes hydrogenated. By choosing the working conditions, the hydrogenation may be stopped at the carbinol stage. According to the example, 2-phenacyl-pyridine (see Specification 311,387) is hydrogenated at ordinary temperature and pressure using a nickel catalyst to give 2-phenylhydroxyethyl-pyridine; on further hydrogenation employing platinum as catalyst, or by using increased pressure and raised temperature with a nickel catalyst, 2- phenylhydroxyethyl-piperidine is produced. The Specification as open to inspection under Sect. 91 (3) (a) also describes the choice of hydrogenation conditions such that only one keto group of the diketo compound becomes reduced to the carbinol stage. This subject-matter does not appear in the Specification as accepted.
