The experiments indicate that under the trial conditions, the iodine numbers of activated carbon produced from anthracite coal are lower than those of from long-flame coal;
Standard test method for granutar activated carbon from coal--Determination of iodine number
The iodine number of the products after distillation is under 1. The product consists of stearic acid and palmitic acid in the ratio of 45:55 or 50:50. It therefore conforms to the specifications as required by the cosmetics industry.
Methods: By using the the methods in Pharmacopoeia to determine the acid number, iodine number, saponification value, specific gravity, refractive index and content.
