16. Paint brushes can be cleaned with acetone, but it is quite messy, so I suggest using disposable brushes. Tritiated leucine was given to some animals, which were killed 3, 8 or 15 minutes later to measure the rate of synthesis of N-nitrosodimethylamine demethylase. (A) Aspirin does not affect folic acid absorption. The particle size selective characteristics are determined by the type of cyclone used together with the sampling flow rate. On oxidation with chromic acid (H2 CrO4 ), It gives a carboxylic acid (B) with molecular formula C7 H6O2 . Learners would have also looked at some of the physical methods of separating different types of mixtures (including hand sorting, sieving, filtration), and this year we will explore some additional methods in more detail (including distillation and chromatography). It can also be prepared by ring-opening polymerization of lactide [–C(CH 3)HC(=O)O–] 2, the cyclic dimer of the basic repeating unit. Octanoic acid is also known as caprylic acid.
