Vegetable oil enzymatic degumming process by means of aspergillus

The content of phosphorus-containing components and the iron content of an edible vegetable or animal oil, preferably an oil such as soybean oil which has been wet-refined to remove mucilage, are reduced by enzymatic decomposition by contacting the oil with an aqueous solution of phospholipases A.sub.1, A.sub.2, or B and then separating the aqueous phase from the treated oil.

Enzymatic treatment of edible oils

A process and reactor are disclosed for the continuous treatment of a turbid liquid with a granular treating agent placed in a fixed bed through which the liquid flows. Preferably, the liquid is whey and the treating agent is lactase immobilized on support particles, and treatment involves hydrolysis of lactose in the whey. During treatment, the flow of whey through the fixed bed is periodically interrupted and a flow of cleansing liquid is passed through the fixed bed countercurrent to the flow of whey. The flow of cleansing liquid is under sufficient hydrostatic pressure to press the fixed bed against moving fragmentation devices to separate and fluidize the support particles into a fluidized bed whereby the support particles containing immobilized lactase are cleansed by removing material deposited thereon from the whey.

Hydrolysis of lactose in whey

What is disclosed are aqueous dispersions of a hydrophilic copolymer prepared by polymerizing, in an aqueous medium, a monomer mixture comprising a member selected from the group consisting of lower alkyl acrylates and methacrylates, a compound of the formula ##STR1## wherein R is hydrogen or methyl, R.sup.1 is hydrogen or alkyl having 1 to 4 carbon atoms. Y is oxygen or --NR.sup.2 --, R.sup.2 is hydrogen or alkyl having 1 to 4 carbon atoms, and n is an integer from 1 to 25, up to 8 percent, by weight of the copolymer, of a member selected from the group consisting of copolymerizable carboxylic acids and salts of such acids, and at least one monomer capable of crosslinking said copolymer, as well as methods for making said dispersions and using them to impart a hydrophilic finish to fibers and fabrics.

Method of finishing fibers or fabrics with dispersions of hydrophilic

Aqueous dispersions of copolymers of (1) acrylic or methacrylic acid esters, (2) derivatives of acrylic acid or methacrylic acid having the general formula ##STR1## wherein Y is oxygen or a --NR'-- group where R' is hydrogen or alkyl having 1-4 carbon atoms, R is hydrogen or methyl, R' is hydrogen or alkyl having 1-4 carbon atoms, and n is an integer from 1 to 25, (3) one or more polymerizable carboxylic acids and/or the salts thereof, and (4) one or more monomers capable of crosslinking the polymer chains. These copolymers are highly water absorbent, and alkali-resistant, and applied as dispersions are well suited for providing a hydrophilic finish to textile fibers and to textiles and non-wovens.

Dispersions of hydrophilic acrylic resins

Non-blocking coatings are disclosed, which coatings comprise an acrylate ester emulsion polymer prepared by polymerization in the presence of a degraded starch which, in a 10 percent solution in 1 N NaOH, has a viscosity not greater than 15 mPa . s at a velocity gradient D=532.1 s.sup.-1.

Method of making aqueous emulsions of acrylate copolymers in the

Aqueous film-forming dispersions of a synthetic resin, said resin containing from 0.5 to 5 percent by weight of a heterocyclic comonomer of the formula ##STR1## wherein A--B is --C.dbd.C-- or --CH--CH--; R.sup.1 is hydrogen or lower alkyl; and R is an aliphatic group having a polymerizable carbon-carbon double bond therein; water-base paints comprising a pigment and filler dispersed in such an aqueous dispersion; and a method for overpainting substrates of oil-base paints or alkyl resin paints with such a water-base paint.

Film forming aqueous synthetic resin dispersions and paints prepared

Method for making highly resin-filled paper on a paper machine employing a fiber slurry having therein a non-ionic resin in an amount of at least 30 percent (dry resin weight based on dry fiber weight), said resin being combined with the fiber slurry as a dispersion comprising a cationic and a non-ionic dispersing agent.
