WebThe Methanone, (4-methoxy-3-methylphenyl) (3-methylphenyl)-, with the CAS registry number 41295-28-7, is also known as 3,3'-Dimethyl-4-methoxybenzophenone. Its EINECS number is 255-300-6. This chemical's molecular formula is C 16 H 16 O 2 and molecular weight is 240.3. WebTo optimize the electrodeposition conditions, the exfoliation of α-zirconium phosphate by tetrabutylammonium (TBA) salts was investigated in several nonaqueous solvents. Acetonitrile was found to be the best solvent for making crack-free, oriented films because of its high vapor pressure, low viscosity, and relatively high permittivity. prohealthlearning prohealthcare.com https://dovetechsolutions.com
