7588 results about "Acyl group" patented technology

An acyl group is a moiety derived by the removal of one or more hydroxyl groups from an oxoacid, including inorganic acids. It contains a double-bonded oxygen atom and an alkyl group (R-C=O). In organic chemistry, the acyl group (IUPAC name: alkanoyl) is usually derived from a carboxylic acid. Therefore, it has the formula RCO–, where R represents an alkyl group that is linked to the carbon atom of the group by a single bond. Although the term is almost always applied to organic compounds, acyl groups can in principle be derived from other types of acids such as sulfonic acids, phosphonic acids. In the most common arrangement, acyl groups are attached to a larger molecular fragment, in which case the carbon and oxygen atoms are linked by a double bond.

Metal oxide particle and its uses

An object of the present invention is to provide a metal oxide particle which exercises more excellent ultraviolet absorbency as a matter of course and combines therewith merits of, for example, either being shifted in ultraviolet absorption edge toward the longer wavelength side and being excellent also in the absorption efficiency of a long-wavelength range of ultraviolet rays, or having good transparency and, for example, even in cases where added into or coated onto substrates, not damaging the transparency or hue of the substrates. As a means of achieving this object, a metal oxide particle according to the present invention is a metal oxide particle such that a hetero-element is contained in a particle comprising an oxide of a specific metal element (M), wherein the metal oxide particle is: 1) a metal oxide particle in the form of a fine particle wherein the hetero-element is at least one specific metal element (M′); 2) a metal oxide particle wherein the hetero-element includes at least two specific metal elements (M′); 3) a metal oxide particle wherein: the hetero-element is a more specified metal element (M′) and at least a part thereof is 2 in valence; or the metal element (M) is a more specified metal element and the metal oxide particle is in a specific range in crystal grain diameter in the vertical direction to each of the (002) plane and the (100) plane; or 4) a metal oxide particle wherein: the hetero-element is at least one specific nonmetal element and an acyl group is contained in the particle; or the hetero-element includes at least two specific nonmetal elements; or the hetero-element is at least one specific nonmetal element and a component derived from a metal element (M′) other than the metal element (M) is contained in the particle.
