This is the third part of a series of reviews on the application of organotin compounds as the catalysts for some important industrial processes, such as (re)esterification and production of polyurethanes. The third review considers the application of organotin compounds as the catalysts for vulcanization of blocked isocyanates and silicones.

In situ DRIFTS was employed to investigate the reaction of hydrogen with supported subnanometer Pt-ReOx species that are active in the hydrogenation of carboxylic acids. Absorption bands of platinum hydrides in the region of 2025–2043 cm^–1 were detected; high reactivity of the hydrides toward the adsorbed acetic acid was revealed. In the process, the absorption band of platinum hydride shifted to high frequencies and increased in intensity due to the influence of adjacent acetates on the electronic state of platinum. It was found that in a hydrogen medium the intensity of platinum hydride bands sharply increases after the adsorption of acetic acid and then gradually decreases owing to the reaction of the hydrides with surface acetates.

Linear alpha olefins (LAO) form a class of chemical compounds that are used in the production of highly marketable products, such as plasticizers, synthetic lubricants, surfactants and (co)polymers with the improved operating characteristics. Since the annual world consumption of LAO derivatives is growing, specialists from research institutes, universities and industrial laboratories become involved in LAO processing. The analysis of scientific literature published in recent ten years revealed the absence of general reviews devoted to LAO processing. This review considers modern trends in the processing of LAO, which contain four and more carbon atoms, to technologically important derivatives. General information on the main products obtained by LAO processing, methods of their production and application fields is reported. The existing technological processes used to obtain LAO derivatives as well as the catalysts employed in the processes are briefly described. The review presents modern trends in LAO processing and promising ways for enhancing the available technologies, particularly the development of new types of catalysts. Authors of the review make no pretence to a comprehensive or detailed presentation of the material; the main aim was to give a general idea of the main directions in LAO processing, the catalysts used in such processes, and the advanced approaches to their improvement.

This review is a continuation of the first part, which considered modern trends in the processing of linear alpha olefins to (co)polymers of ethylene, anionic and non-ionic surfactants. Important directions in LAO processing are briefly described: alkylation leading to the formation of linear alkylbenzenes, oligomerization of alpha olefins to poly alpha olefins, sulfation yielding alpha olefin sulfonates, and other bulky processes.

Novel catalysts with the composition Cd-(Zn)/TiO₂ and Cu-(Zn)/TiO₂ containing nanodispersed titanium(IV) oxide were synthesized and characterized using X-ray diffraction analysis, low-temperature nitrogen adsorption and temperature-programmed reduction in hydrogen. Activity of the synthesized catalysts toward steam reforming of methanol was studied in a microchannel reactor. The highest activity was observed for the Cd-containing catalysts; in addition, they showed the lowest selectivity to carbon monoxide. The catalytic and physicochemical properties of the tested catalysts were compared. A correlation was found between activity of the catalysts and their ability to partial hydrogen reduction of Ti⁴⁺ cations to Ti³⁺ in the TiO₂ support. Supposedly, the ability to reduce titanium cations depends on semiconductor properties of the oxides in the catalyst.
