Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 174 words
The process for the production of organic alkali metal compounds and resinous products by mixing and reacting the following components: A. Oxidated silicon compound in the amount of 50 to 100 parts by weight and selected from the group consisting of hydrated silica, sodium silicate, potassium silicate, natural oxidated silicon compounds containing free silicic acid radicals and mixtures thereof; B. Alkali metal compound in an aqueous solution in the amount of 50 to 100 parts by weight and selected from the group consisting of sodium hydroxide, potassium hydroxides, alkali metal carbonates selected from the group consisting of sodium carbonate, potassium, and mixtures thereof; C. Organic compound which is attached to a substituent which will split off during the reaction is a substituted hydrocarbon which contains a substituent selected from the group consisting of halogen acid sulfate, nitrate, acid phosphate, bicarbonate, formate, acetate, propionate, laurate, oleate, stearate oxlate, acid malonate, acid tartrate, acid citrate and mixtures thereof, and is added in an amount wherein the substituted radicals are about equal to the alkali metal readicals.
Claim 2
Dependent Claim 174 words
The process for the production of organic alkali metal compounds and resinous products by mixing and reacting the following components: A. Oxidated silicon compound in the amount of 50 to 100 parts by weight and selected from the group consisting of hydrated silica, sodium silicate, potassium silicate, natural oxidated silicon compounds containing free silicic acid radicals and mixtures thereof; B. Alkali metal compound in an aqueous solution in the amount of 50 to 100 parts by weight and selected from the group consisting of sodium hydroxide, potassium hydroxides, alkali metal carbonates selected from the group consisting of sodium carbonate, potassium, and mixtures thereof; C. Organic compound which is attached to a substituent which will split off during the reaction is a substituted hydrocarbon which contains a substituent selected from the group consisting of halogen acid sulfate, nitrate, acid phosphate, bicarbonate, formate, acetate, propionate, laurate, oleate, stearate oxlate, acid malonate, acid tartrate, acid citrate and mixtures thereof, and is added in an amount wherein the substituted radicals are about equal to the alkali metal readicals.
Claim 3
