Experimental data from various Uterature sources indicate that the maximum yield of DMSS is approximately 80% relative to the quantity of methoxide utilized, regardless of the reaction solvent employed in its synthesis. Various attempts to improve the yield efficiency and consequently the economics of quinacridone production have been ineffective but have resulted in the discovery of some of the competing side reactions based on the identification the corresponding isolated by-products. Therefore, it is of interest to consider the latter and the potential modes of their formation.
