General description

Accurate analytic results in UV/VIS and infrared spectroscopy depend on the use of very pure solvents for sample preparation. The Uvasol<TMSYMBOL></TMSYMBOL> solvents range has been specially designed for spectroscopy and other applications requiring solvents of the highest spectral purity. The refinement process allows a greater degree of security in applications and avoids misinterpretation of analytical results caused by traces of UV, IR and fluorescence contamination. Uvasol<TMSYMBOL></TMSYMBOL> solvents offer best UV transmittance. In all specifications the minimum transmittance for 5 typical wavelengths are identified.

Application

Numerical Simulation of HCCI Combustion Fuelled with Gasoline + Methyl Tert-Butyl Ether Blend.: This study uses numerical simulations to investigate the effects of adding MTBE to gasoline in homogeneous charge compression ignition (HCCI) engines, highlighting improvements in combustion efficiency and emissions reduction (Dadapeer et al., 2022).

INFLUENCE OF NANO CERIUM OXIDE IN EMISSION REDUCTION WITH METHYL TERT-BUTYL ETHER - GASOLINE BLENDS AT HCCI ENGINE.: This paper investigates the impact of nano cerium oxide on reducing emissions in gasoline blends with MTBE in HCCI engines, showing significant improvements in emission reduction (International Journal of Renewable Energy Research, 2023).

Pt/Au Nanoparticles@Co3O4 Cataluminescence Sensor for Rapid Analysis of Methyl Sec-Butyl Ether Impurity in Methyl Tert-Butyl Ether Gasoline Additive.: This research presents a sensor based on Pt/Au nanoparticles for detecting MSBE impurities in MTBE, offering a rapid and reliable method for ensuring the purity of MTBE gasoline additives (Shi et al., 2022).
