A refined electrical insulating oil and oil-filled electrical appliances impregnated therewith. The electrical insulating oil is quite suitable for use in oil-filled electrical appliances in which insulating materials or dielectric materials made of plastics are employed. The electrical insulating oil is prepared by refining a mixture of unsaturated dimers of styrenes and alkylbiphenyls and/or alkylnaphthalenes, using a solid acidic substance.

The present invention relates to a liquid, cleaning and/or cleansing composition comprising abrasive cleaning particles.

Liquid Cleaning And/Or Cleansing Composition

A method for bleach-whitening of synthetic textile material is provided comprising contacting said textile material with (a) an enzymatic textile bleaching composition comprising (i) a perhydrolase enzyme, (ii) an ester substrate for said perhydrolase enzyme, (iii) a hydrogen peroxide source, (iv) a surfactant and/or an emulsifier, (v) a peroxide stabilizer, (vi) a sequestering agent, (vii) a buffer which maintains a pH of about 6 to about 8, and (b) at least one fluorescent whitening agent, and, optionally, (c) at least one acid or disperse shading dye for shaded variations of white, for a length of time and under conditions suitable to permit measurable whitening of the textile material, thereby producing a bleached-whitened textile material.

Enzymatic textile bleach-whitening methods

The present invention provides the new bis-stilbene compounds, which are useful as optical brighteners and correspond to the formula R.sub.1 -- CH = CH -- X -- CH = CH -- R.sub.2 in which X represents a diphenyl residue bound in positions 4 and 4' to the =CH-- groups; R 1 and R 2 independently of each other, each represents a monocyclic benzene residue, a diphenyl, naphthyl or pyridyl residue, and in which at least one of the cyclic systems R 1 , R 2 , X contains a possibly functionally modified sulphonic acid group, a sulphone group, a possibly functionally modified carboxylic acid group, a nitrile, hydroxyl, mercapto or methyl group.

Bis-stilbene compounds

The invention provides a new process for the manufacture of aromatic compounds which at least once contain a benzene ring of an aromatic carbocyclic ring system bonded by an ethylene double bond in conjugation with a further aromatic ring system, i.e. contain the stilbene skeleton or stilbene analogon as central structural element, as well as certain classes of new compounds of this type. The process is characterized by the reaction of a Schiff base of an aromatic aldehyde with an aromatic carbocyclic six-membered ring compound which contains one to four methyl groups bonded to ring carbon atoms of a benzene ring, which furthermore contains aromatic rings which are exclusively six-membered carbocyclic rings, and wherein those benzene rings whose methyl groups are to be caused to react are free of other substituents which contain atoms which are replaceable by alkali metal. The reaction is carried out in the presence of (a) a strongly basic alkali compound and (b) an N-dialkyl-acylamide as solvent. The compounds obtainable according to this process show a marked fluorescence emission and therefore are suitable for all purposes where fluorescence properties are used, as for instance optical brighteners, scintillators fluorescence dyes, etc.

Cationic fluorescent whitening agents of the formula ##STR1## wherein B is a fluorescent whitening agent containing basic tertiary amino groups, m is the number of basic amino groups, and each of R 1 , R 2 and R 3 is alkyl of 1 to 4 carbon atoms which is unsubstituted or substituted by non-chromophoric groups, or is alkenyl of 2 to 4 carbon atoms which is unsubstituted or substituted by non-chromophoric groups These compounds have good solubility in water and they make it possible to prepare concentrated solutions and can be used for whitening organic material

Cationic fluorescent whitening agents

Detergents which, besides inorganic and/or organic peracids, contain specific stilbene compounds as optical brighteners. These detergents are stable for several months and display the customary cleaning properties even at washing temperatures of 20-60 DEG C.

Stable detergents containing optical brighteners

Detergents which, in addition to inorganic and/or organic peracids, contain specific stilbene compounds as fluorescent whitening agents. These detergents are stable for several months and already show the customary cleaning properties at washing temperatures of 20°-60° C.
