With sophisticated information processing technologies, a multiplicity of information devices are used in a variety of scenes in the society. Then, an enormous quantity of information is printed by printers. Particularly over the recent years, images captured by digital cameras etc are printed by color printers in the great majority of cases. The color print involves especially a large quantity of toner consumption.
Accordingly, a running cost that depends upon the toner consumption is not ignorable nowadays. This being the case, a scheme for saving the toners has hitherto been proposed.
What is known as a toner save technology for this purpose is a method of extracting an outline of character/graphic data after being developed on, e.g., a bitmap memory. This method serves to restrain a quantity of toners by diminishing a dot size of an internal area or the outline of the character/graphic data (which may be called a prior art 1).
Another known method is that the toner quantity is restrained by thinning out at a fixed ratio the data after similarly being developed on the bitmap memory (wherein the dots

If the reaction is carry out without extra solvent, i.e. if the dialkyl disulfide is used as solution: an excess of dialkyl disulfide or of a dialkyl disulfide mix is used, subsequent distillative recovery being potential. The intersection is purified, for model, by distillation or crystallization (for exercise from diisopropyl ether).
