Usage

General Description

2-Butenedial, also known as crotonaldehyde, is a highly reactive and flammable organic compound commonly used in the production of chemicals and plastics. It is a colorless liquid with a strong, unpleasant smell and is soluble in water, alcohols, and other organic solvents. 2-Butenedial is classified as a substance of very high concern due to its potential to cause cancer, skin irritation, and respiratory issues in humans. It is also known to have harmful effects on aquatic organisms and the environment. Therefore, proper handling and disposal of 2-butenedial are crucial to minimize its impact on human health and the ecosystem.

Comparative studies of the photocatalytic and microwave -assisted degradation of alizarin red using ZnO/poly(1- naphthylamine) nanohybrids

Semiconductors such as ZnO and TiO2 have been extensively utilized in the photocatalytic degradation of dyes. However till date, no study has been reported to compare the catalytic efficiency of such organic-inorganic hybrids under UV light and microwave irradiation separately. The present work reports the synthesis of poly(1-naphthylamine)/ZnO nanohybrids. The structure and morphology of the synthesized nanocomposites were characterized using FT-IR, UV, XRD, TEM and Cyclic voltammetry analyses. The dye degradation studies were done separately in a photochemical reactor and in laboratory microwave oven and the fragments were identified using LC-MS technique. Results showed that under microwave irradiation, the efficiency of ZnO/PNA as catalyst was higher as compared to UV irradiation. Higher extent of ?OH radical generation was confirmed in microwave as compared to UV irradiation which was found to be responsible for the high rate of degradation of dye solution. A plausible degradation pathway was proposed.

Catalytic oxidation of furan and hydrofuran compounds. 6. Oxidation of furan by hydrogen peroxide in the presence of vanadium compounds under the conditions of phase-transfer catalysis

Oxidation of furan in system containing hydrogen peroxide, vanadium compound, chlorinated hydrocarbon, water, and phase-transfer catalyst was studied for the first time. In addition to the main product of this process - cis-β-formylacrylic acid - the form

Reactions of catalytic oxidation of furan and hydrofuran compounds. I. General principles of the oxidation of furan in the system hydrogen peroxide-vanadium(IV) compounds depending on the type of solvent and catalyst

The oxidation of furan by aqueous hydrogen peroxide catalyzed by vanadium(IV) compounds was studied in homogeneous aqueous alcohol medium and a heterogeneous system in the presence of tridecylmethylammonium chloride. The optimum conditions of the process were determined for both versions. It was shown that they are similar in direction, duration, and degree of conversion of furan. At the same time, the composition and total yield of the products, as well as their yields in the organic and aqueous phases, depend on the type of solvent and vanadium catalyst. 1996 Plenum Publishing Corporation.
