Calcium sulfate CaSO4 that has uses as white pigment or gypsum, and HCl aq. or gaseous, may be produced from conc. H2SO4 and solid CaCl2, Solvay process waste.
Water saving technology of baking soda NaHCO3, best for cleaning, from brine NaCl, and crystalline ammonium bicarbonate NH4HCO3; no waste, contrary to Solvay process.
Method of manufacturing of new analogues of 24-dehydro-1,25-dihydroxycholecalciferol and 24-dehydro-1,25-dihydroxyergocalciferol, Polish Patent, 23.05.1993 (to Institute of Pharmaceutical Industry), Patent Appl. P-284259, M. Chodynski, A. Kutner, H. S. Salwa, T. Ryznar, J. Król-Bogomilski,
Two new sesquiterpenoid lactones from Lactarius necator, W. M. Daniewski, M. Kocór, J. Król, Bull. Acad. Polon. Sci., Ser. Sci. Chim., 23, 637 (1975).
Sesquiterpenes with the lactarane (as in lactarorufin A) and secolactarane skeleton in the molecules were isolated from the title mushroom and their structure elucidated.
Lactarorufin N and revised structures of lactarorufines, W. M. Daniewski, M. Kocór and J. Król, Roczniki Chem.,50, 2095, (1976).
Further metabolite of Lactarius necator, sesquiterpene with the lactarane skeleton in the molecules was isolated and its structure elucidated. The structures of previously investigated sesquiterpenes have been revised.
Structure of 3-deoxylactarorufin A, W. M. Daniewski, M. Kocór and J. Król, Roczniki Chem., 51, 1395, (1977).
Sesquiterpene with the lactarane skeleton in the molecules was isolated from the common mushroom Lactarius necator and its structure elucidated.
No waste, water saving technology (contrary to Solvay process) of production and applications of calcium chloride (from soda production), many uses of CaCl2.
A modified process for the production of sodium bicarbonate and soda ash comprising the utilization of waste products, Ma.E. B. Borkowski, Dr. Jerzy Król-Bogomilski, Chemik, 45 (5), 121, (1992).
Sodium hydrogen carbonate (best for cleaning) may be produced almost without waste using water saving industrial solution that starts from brine and crystalline NH4HCO3. Resulting NH4Cl yields with solid CaO or Ca(OH)2 solid calcium chloride CaCl2 that has many uses.
