5105 results about "Double bond" patented technology

A double bond in chemistry is a chemical bond between two chemical elements involving four bonding electrons instead of the usual two. The most common double bond occurs between two carbon atoms and can be found in alkenes. Many types of double bonds exist between two different elements. For example, in a carbonyl group with a carbon atom and an oxygen atom. Other common double bonds are found in azo compounds (N=N), imines (C=N) and sulfoxides (S=O). In skeletal formula the double bond is drawn as two parallel lines (=) between the two connected atoms; typographically, the equals sign is used for this. Double bonds were first introduced in chemical notation by Russian chemist Alexander Butlerov.

Method of forming amorphous carbon film and method of manufacturing semiconductor device using the same

The present invention relates to a method of forming an amorphous carbon film and a method of manufacturing a semiconductor device using the method. An amorphous carbon film is formed on a substrate by vaporizing a liquid hydrocarbon compound, which has chain structure and one double bond, and supplying the compound to a chamber, and ionizing the compound. The amorphous carbon film is used as a hard mask film.
It is possible to easily control characteristics of the amorphous carbon film, such as a deposition rate, an etching selectivity, a refractive index (n), a light absorption coefficient (k) and stress, so as to satisfy user's requirements. In particular, it is possible to lower the refractive index (n) and the light absorption coefficient (k). As a result, it is possible to perform a photolithography process without an antireflection film that prevents the diffuse reflection of a lower material layer.
Further, a small amount of reaction by-product is generated during a deposition process, and it is possible to easily remove reaction by-products that are attached on the inner wall of a chamber. For this reason, it is possible to increase a cycle of a process for cleaning a chamber, and to increase parts changing cycles of a chamber. As a result, it is possible to save time and cost.

Dimerized alcohol compositions and biodegradible surfactants made therefrom having cold water detergency

There is provided an alcohol composition obtained by dimerizing an olefin feed comprising C6-C10 linear olefins to obtain C12-C20 olefins, followed by conversion to alcohols, such as by hydroformylation. The composition has an average number of branches ranging from 0.9 to 2.0 per molecule. The linear olefin feed preferably comprises at least 85% of C6-C8-olefins. The primary alcohol compositions are then converted to anionic or nonionic surfactants, preferably sulfated or oxyalkylated or both. The sulfated compositions are biodegradable and possess good cold water detergency. The process for making the dimerized primary alcohol comprises dimerizing, in the presence of a homogeneous dimerization catalyst under dimerization conditions, an olefin feed comprising C6-C10 olefins and preferably at least 85 weight % of linear olefins based on the weight of the olefin feed, to obtain a C12-C20; optionally double bond isomerizing said C12-C20 olefins; and converting the C12-C20 olefins to alcohols, preferably through hydroformylation. The process is preferably a one-step dimerization. The homogenous catalyst comprises a mixture of a nickel carboxylate or a nickel chelate, with an alkyl aluminum halide or an alkyl aluminum alkoxide.
