  • Patent number: 4647678
    Abstract: The epoxidation of terminally and/or internally olefinically unsaturated hydrocarbon compounds which are liquid at 50.degree. to 100.degree. C. and at atmospheric pressure (oil phase), in which the oil phase is treated with an acid phase containing acetic acid, hydrogen peroxide and peracetic acid in aqueous solution, after which the aqueous acid phase is separated from the oil phase, the peracetic acid in the aqueous acid phase is regenerated and the regenerated aqueous acid phase is returned to the epoxidation reactor. Epoxidation is carried out using an aqueous acid phase containing at most about 10% by weight of peracetic acid, and the peracetic acid content in the aqueous acid phase is reduced by at most about 50%, based on the peracetic acid content of the aqueous acid phase used, after a single passage through the epoxidation stage. After separation from the oil phase, the aqueous acid phase preferably is cooled before regeneration.

  • Patent number: 4642108
    Abstract: A tampon for feminine hygiene consists of a cylindrically-compressed length of a strip of cottonwool or rayon staple or a combination thereof which is wrapped with an overlap in a fluff-free or fuzz free covering material, said strip being cut into the required lengths together with the covering material perpendicularly to the overlap line, and a recovery thread attached to the length of a strip of cottonwool or rayon staple or a combination thereof. The problem which the invention solves is to prevent fibers from breaking loose from the exposed cut edges. According to the invention, the exposed cut edges are folded onto the surface of the length of a strip of cottonwool or rayon staple or a combination thereof after it has been separated and compression is carried out in such a way that the exposed cut edges are situated inside the tampon.
