US Classification:

523102

Abstract:

Described is a composition of matter particularly useful in fabricating toilet rim blocks consisting of: (a) extruded polyvinyl alcohol or partially hydrolyzed polyvinyl acetate with the maximum mole ratio of acetyl moiety:hydroxyl moiety being about 3:1 having a number average molecular weight of from about 15,000 up to about 68,000 containing 0 up to about 13% by weight of plasticizer; (b) from about 1 up to about 20% by weight of a compatible fragrance contained within the polyvinyl alcohol or partially hydrolyzed polyvinyl acetate; (c) from 0 up to about 20% by weight of a "foaming agent" which is a first surfactant and which can be a detergent, contained within the polyvinyl alcohol or partially hydrolyzed polyvinyl acetate; (d) from 0 up to about 20% by weight of a hydrophobic silica contained within the polyvinyl alcohol or partially hydrolyzed polyvinyl acetate; (e) from 0 up to about 20% by weight of at least one second surfactant in addition to the "foaming agent"; (f) from 0 up to about 5% by weight of a water soluble dye; and (g) from 0 up to about 4% by weight of a "foam booster". Also described are processes for preparing such compositions of matter and such toilet rim blocks. When used for the fabrication of toilet rim blocks, the maximum mole ratio of acetyl moiety:hydroxyl moiety is about 1:3.

Abstract:

Flue gas is desulfurized by absorbing it onto a selective absorbent-catalytic material. The absorbed SO. sub. 2 is recovered by contacting it in a desorption cycle with a reducing desorption gas. In one embodiment, multiple absorbent beds are employed and alternate absorption-desorption cycles are used in each of the multiple beds with the flue gas and the desorption gas used alternately. The sulfur oxide is recovered in concentrated form in the desorption gas stream and is then utilized as feed in a conventional sulfuric acid plant yielding concentrated sulfuric acid.
