  • Patent number: 10988590
    Abstract: A coated, highly transparent film based on cellulose triacetate, is proposed that includes a) a support film acting as support layer and a cellulose triacetate or a mixture of cellulose esters and cellulose triacetate as main component, the cellulose triacetate or mixture being defined by a haze value of <0.5%, measured on the cellulose triacetate or mixture drawn out to a film after having been dissolved in dichloromethane or acetone, and b) a multi-functional coating applied in a coating solution to one or both sides of the support film. A dissolver medium can also be used as an enclosure medium. The highly transparent films of the invention can be used as window film, sunglasses film, laminating film, furniture foil, enclosing film, slide film for microscopy, cover slip replacement film and/or protective film, adhesive to glass, wood, metal, ceramic, cellulose derivative films or plastics following incipient dissolution or heat treatment.

  • Patent number: 10577548
    Abstract: An enhanced diluent (EDIL) composition used to prepare a transportable dense crude oil composition is disclosed. An EDIL composition contains a usually used dense crude hydrocarbon diluent (DIL) plus an additive (ADD) composition that permits the amount of EDIL used in the resulting diluted transportable dense crude (EDIL:DC) to be lessened by about 20 to about 60 percent, while maintaining the viscosity and other properties of the usually used DC:DIL composition. A contemplated ADD composition is a mixture of three components, a solvent mixture, a diol and a surfactant. A contemplated EDIL composition contains about 1 to about 20 percent by weight of the ADD composition. Admixture of EDIL with a dense crude at about 80 to about 40 percent by volume of the amount of DIL usually used provides an easily transportable enhanced dense crude composition. A method of preparing a transportable dense crude composition is also disclosed.
