Classifications tests

To qualify for the CCMC categories G and D, oil must meet the requirements of the following tests in addition to the relevant API classification tests.

When unknown compounds are identified without the aid of spectroscopy classification tests are used. Reacting the carbonyl in a ketone or aldehyde with an amine (2,4 dinitro-phenylhydrazine) to form an inline is the easiest way to detect a ketone or aldehyde (Reaction l). The iinine that forms is a highly colored solid. The color of the solid also helps to indicate structural characteristics. Ketones and aldehydes with no conjugation tend to form itnines with yellow to orange colors, while highly conjugated ketones or aldehydes form imines with red color. 

The presence of a colored solid confirms the presence of a ketone or aldehyde, but the imine formation does not indicate whether the unknown is a ketone or aldehyde. A second classification test is used to distinguish the two functionalities. This test is called the Tpllens test, and die significant reaction is shown in Reaction 2. 

The classification tests (summarized in Table 31.2), when properly done, can distinguish between various types of aldehydes and ketones. However, these tests alone may not allow for the identification of a specific unknown aldehyde or ketone. A way to correctly identify an unknown compound is by using a known chemical reaction to convert it into another compound that is known. The new compound is referred to as a derivative. Then, by comparing the physical properties of the unknown and the derivative to the physical properties of known compounds listed in a table, an identification can be made. 

Classification tests are to be carried out on four known compounds and one unknown Any one test should be carried out on all five samples at the same time for comparison. Label test tubes as shown in Table 31.3.

First, sheet corrugated board was shown to perform well in absorbing shock in tests in which three sheets of corrugated board were put into a small case and the cases used as shock absorbers for preventing the propagation of explosion from a detonator. Second, the safety of the new package was shown by applying the United Nations classification tests for explosives.

NOTE 3 For classification tests on solid substances or mixtures, the tests should be performed on the substance or mixture as presented. If for example, for the purposes of supply or transport, the same chemical is to be presented in a physical form different from that which was tested and which is considered likely to materially alter its performance in a classification test, the substance or mixture must also be tested in the new form.
