Acetylene sludge comes from the production of acetylene gas which is produced in large quantities from industrial plants. Since acetylene sludge waste has a baling and mortar properties as well as lime derivative products, they can be used as substitutes ... see more

This paper presents the results of a study on the catalytic activity and selectivity of nickel and palladium catalysts in hydrogenation reactions of nitro- and acetylene compounds. It was shown that the activity and selectivity of nickel catalysts in the ... see more

Some vegetable seeds need a very long time to germinate. In these kinds of seeds the second phase of germination is very long. As acetylene’s chemical structure is almost similar to the gaseous hormone ethylene, its’ physiological effect on seed germinati... see more

Acetylene sludge comes from the production of acetylene gas which is produced in large quantities from industrial plants. Since acetylene sludge waste has a baling and mortar properties as well as lime derivative products, they can be used as substitutes ... see more

A synthesis of potentially biologically active heterocyclic amino alcohols of acetylene (Piperidine and Morpholine) under the conditions of Mannich reaction accomplished and received their acyl derivatives. Pharmacological activity (antibacterial and anti... see more

The Ru-based catalysts, including Ru/AC (activated carbon), TPAP (tetrapropylammonium perruthenate)/AC, TPAP/AC-HNO3, and TPAP/AC-HCl, were prepared and assessed for the direct synthesis of vinyl chloride monomer. The results indicate that the TPAP/AC-HCl... see more

The iminodiacetic acid-modified Nieuwland catalyst not only improves the conversion of acetylene but also increases the selectivity of monovinylacetylene (MVA). A catalyst system containing 4.5% iminodiacetic acid exhibited excellent performance, and the ... see more

Recently, many scientists have focused on the development of green industrial technology. However, the process of synthesizing vinyl chloride faces the problem of Hg pollution. Via a novel approach, we used two elements Mo and Ti to prepare an inexpensive... see more

Ammonium hexachlororuthenate ((NH4)2RuCl6) complex was used as a catalyst precursor and coconut activated carbon (AC) was used as the support in the preparation process of the Ru-based catalyst. (NH4)2RuCl6/AC catalyst was prepared via an incipient wetnes... see more
