| titleOfInvention | Method of producing pearlescent basic lead carbonate pigment |
| abstract | A PEARLESCENT PIGMENT CONSISTING OF HEXAGONAL PLATELETS OF BASIC LEAD CARBONATE IS PRODUCED BY BUBBLING CARBON DIOXIDE GAS INTO AN AQUEOUS SOLUTION OF A BASIC LEAD SALT WHICH IS DERIVED FROM THE REACTION OF LEAD MONOXIDE WITH AND ACID. THE ACID THAT IS REACTED WITH THE LEAD MONOXIDE CAN BE NITRIC ACID, BUT MORE PREFERABLY WILL HAVE THE GENERAL FORMULA: X-CH2-CH(-X)-COOH WHEREIN X IS A MEMBER FROM THE GROUP CONSISTING OF HYDROGEN METHYL AND HALOGEN. REACTION OF THE CARBON DIOXIDE WITH THE BASIC LEAD SALT IS CARRIED OUT IN THE PRESENCE OF AN ALCOHOL DISSOLVED IN THE AQUEOUS REACTION MEDIUM, THUS FACILITATING CONTROL OVER THE RATE AND EXTENT OF CRYSTAL INITIATION AND GROWTH. THE RESULTING BASIC LEAD CARBONATE PIGMENT CAN BE INCORPORATED INTO PLASTICS, LACQUERS, AND THE LIKE TO PROVIDE ARTICLES HAVING THE APPEARANCE OF NATURAL PEARL. |
