A paint thinner is a diluent solvent used to dilute oil-based paints or varnish. [ 1 ] [ 2 ] In this context, to dilute is also known as to 'thin'. Solvents labeled "paint thinner" are usually white or mineral spirits .
HMPA is a specialty solvent for polymers, gases, and organometallic compounds. It improves the selectivity of lithiation reactions by breaking up the oligomers of lithium bases such as butyllithium. Because HMPA selectively solvates cations, it accelerates otherwise slow S N 2 reactions by generating more bare anions.
The second active ingredient is an organic solvent such as 2-butoxyethanol (ethylene glycol monobutyl ether, trade name butyl cellosolve) that acts as a wetting agent and provides a protective primer layer in conjunction with an organic polymer emulsion.
N,N′-Dimethylpropyleneurea (DMPU) is a cyclic urea sometimes used as a polar, aprotic organic solvent. Along with the dimethylethyleneurea, it was introduced as an analog of tetramethylurea. [2] In 1985, Dieter Seebach showed that it is possible to replace the suspected carcinogen hexamethylphosphoramide (HMPA) with DMPU. [3]
At elevated temperature and in the presence of a palladium catalyst, hydrogenolysis of dihydrolevoglucosenone via levoglucosanol selectively yields tetrahydrofuran-2,5-dimethanol (THF-dimethanol), [8] which is a biodegradable solvent and a bio-based precursor to 1,6-hexanediol (and 1,6-diaminohexane).
Methylethyl ketone oxime is the organic compound with the formula C 2 H 5 C(NOH)CH 3.This colourless liquid is the oxime derivative of methyl ethyl ketone. MEKO, as it is called in the paint industry, is used to suppress "skinning" of paints: the formation of a skin on paint before it is used.
