1. Solvents are used instead of alkalis, if they are more convenient or faster acting, particularly butoxy ethanol on heat modified soils and methylene chloride on carbonised grease.
2. Typical examples are biro marks (methylated spirits), nail varnish, certain dyestuffs and lipstick (acetone) and paint (methylene chloride).
3. Methylene chloride is a powerful chemical used for the removal of heavy grease deposits and as a paint stripper.
4. The solvent used tends to be methylene chloride thickened with SCMC to a gel consistency to slow down the evaporation of the solvent and to make the product easy to apply.
5. A particular feature of methylene decarbonisers is that they can be used safely on aluminium, copper, brass and other metals normally badly corroded by alkalis.
6. There are several types available; those containing methylene chloride are quick acting and are usually free from caustic or acid and will not harm the wood.
7. They also have experience using a wide range of solvents: methylene chloride, dimethyl formamide, dimethyl sulphoxide and dimethyl acetamide as well as the common alcohols and aromatics.
8. Early solvents included ethanol, hexane and methylene chloride.
9. Goddard and others have proclaimed that quantum chemistry came of age in 1970 on the basis of predictions on the geometry of the methylene molecule.
10. The carbide then reacts with hydrogen on the surface to give a methylene (CH,).
11. Where these materials have to be cleaned methylene chloride is the only chemical option once items are soiled.
12. In 1944 he discovered methylene (CH 2 ) - a remarkable discovery indeed.
13. One compound based on methylene chloride also incorporates ammonium hydroxide to give it a characteristic smell.
