Beschreibung

General description

Benzene (C₆H₆) is an organic compound. It is widely used as a solvent in the production of industrial chemicals (such as cyclohexane, cumene, and styrene), and adhesives. Additionally, several types of rubber, lubricants, dyes, detergents, drugs, and pesticides are made using benzene.

EMPARTA solvents are designed for routine chemical synthesis, drying, purification, and critical labware cleaning in quality control environments. Engineered for precision, they deliver consistently reproducible results essential for rigorous validation and documentation.

Exceptional Quality Standards: These solvents meet or exceed ACS specifications, providing assurance of high quality that is crucial for accurate testing and analysis in quality control.

Consistent Reproducibility: Designed for precision, the solvents ensure that results can be reliably reproduced, which is vital for maintaining compliance and integrity in quality control processes.

Versatile Applications: Suitable for a variety of QC tasks, including analytical testing, method validation, and testing USP/NF monographs, these solvents support a comprehensive approach to quality assurance in laboratory settings.

Application

Benzene can be used:

• As a starting material to produce ethylbenzene with the gaseous ethylene in presence of Friedel-Crafts catalysts (aluminum chloride).
• As a starting material to produce cumene by catalytic alkylation with propylene.
• As a reactant in the production of cyclohexane under mild condition using Ru/ carbon nanotubes (CNTs) catalysts by hydrogenation method.
• To synthesis phenol using H₂O₂ as an oxygen source and nickel(II)complex as a catalyst by hydroxylation method.
• As a solvent along with hexafluoro benzene to obtain stabilized graphene sheet.
