Question

Crime scene investigators have determined that an acrylic spray paint (polymethylmethacrylate, PMMA) was used to deface the Mona Lisa. Leonardo used linseed oil. We would like a solvent that interacts more strongly with acrylic than with linseed oil. Based on their chemical structures, we can approximate the SSCED parameters of linseed oil as n-hexadecane and acrylic paint as methylethylketone. Do you recommend CHCl_3, toluene, or acetone as the solvent? Explain.

Answer 1

WE CAN USE ANY OF THE ABOVE 3 SOLVENTS FOR THE SAID PURPOSE.

HE EXPLANATION IS GIVEN BELOW.

the use of chloroform is NO objectionable, an alternative ALSO is to dissolve the lipid(s) in tertiary butanol or cyclohexane.

This indicates that these films exhibit hydrophilic properties that can be used on self-cleaning surfaces and antifogging mirrors. Heterogeneous photocatalytic oxidation allows the oxidation of airborne volatile organic compounds (VOCs) into carbon dioxide and water in the presence of a semiconductor catalyst and UV light source. Titanium dioxide, due to its chemical stability, nontoxicity, and low cost, represents one of the most efficient photocatalysts. Photocatalytic activity of the TiO2 thin films was evaluated by using toluene and results showed that this film is successful in decomposing toluene.

acetone or white spirit) can be used equally as thinners, though not all. Some may be needed only occasionally and then only for special purposes so it's often difficult to remember what each can do.
