[Class 2 (iii.] Dihydropyran is treated in the liquid phase under anhydrous conditions with a Friedel- Crafts catalyst to form liquid or solid polymers. Polymerization may be effected in a solvent, e.g. a 40‹C.-90‹C. petrol fraction, methylene chloride, ethylene dichloride, carbon disulphide or tetrahydropyran. Suitable catalysts are aluminium and ferric chlorides, hydrogen fluoride and boron trifluoride or its hydrate (BF  3 .2H  2 O). The temperature may range from -40‹C. to 100‹C. The polymers may be further heated at temperatures above 100‹C. in the presence of the catalyst to increase their molecular weight. The original catalyst is removed or destroyed before the further heating by washing with boiling water or by addition of ammonia and the solvent, if present, is also removed. In an example boron trifluoride hydrate was added to a stirred mixture of dihydropyran and methylene chloride at - 40‹C. After 3 hours the product was poured into boiling water to form an emulsion which was cooled and extracted with methylene chloride, the solvent being separated from the extract to yield a solid resin.

Patent GB-582982-A (GB)
Title: Improved process for the production of sulfurized lubricating oils
IPC: C10M101/02
Filed: 1943-05-26
Abstract: Sulphurized lubricating oils having cutting oil characteristics are prepared by heating mineral lubricating oil with sulphur in the presence of a small amount of a sulphurization promoter containing a polybasic acid radicle to a temperature not higher than 250 DEG  F. Suitable sulphurization promoters are sulphuric acid, phosphoric acid, and the water- or oil-soluble sodium salts of sulphonic acids obtained from the acid sludge resulting from the treatment of mineral lubricating oils with fuming sulphuric acid.  Where sulphuric acid is used as the sulphurization promoter, the acidified oil-sulphur mixture may be neutralized with caustic soda before or after heating to sulphurization temperature.  The finished cutting oils may contain fatty substances such as oleic acid.  In examples, (a) mineral lubricating oil is lightly sulphonated, any tar is removed and, if desired, additional mineral lubricating oil is added; the oil is then heated with sulphur and neutralized, if desired, with caustic soda and finally oleic acid is added, (b) phosphoric acid or the water- or oil-soluble sulphonates obtained from the action of fuming sulphuric acid on mineral lubricating oil are added to mineral lubricating oil, the oil is heated with sulphur and oleic acid is then added.  For comparison purposes, the preparation of cutting oils by heating mineral lubricating oil with sulphur in the absence of a sulphurization promoter or in the presence of sodium hydrosulphide is described.  Specifications 464,644 and 510,926 and U.S.A. Specification 2,001,861 are referred to.  The Specification as open to inspection under Sect. 91 refers generally to the process of sulphurizing an oil in presence of a small amount of a sulphurization promoter.  This subject-matter does not appear in the Specification as accepted.
