Iodine quantity is outlined given that the milligrams of iodine adsorbed by one particular gram of carbon if the iodine concentration in the residual filtrate is in a focus of 0.02 regular (i.e. 0.02N). Basically, iodine variety is actually a evaluate in the iodine adsorbed in the pores and, therefore, is an indication from the pore quantity obtainable while in the activated carbon of curiosity. Commonly, drinking water-cure carbons have iodine numbers starting from 600 to 1100. Frequently, this parameter is applied to find out the degree of exhaustion of the carbon in use.
另外，氫氧化鈉是一種鹼，可提供氫氧根離子，可催化羥醛縮合反應。首先，氫氧根離子會去質子化醛或酮，生成烯醇負離子和水，該烯醇負離子會進攻令一電中性的醛或酮，生成羥醛加成物負離子。然後加成物會質子化，在第一步所生成的水上拿掉質子，在生成最終的羥醛產物後，亦同時再生氫氧根離子（催化劑）。
