  • 1-hydroxy-2-O-acyl-sn-glycero-3-phosphocholine compounds, preparation process, antifouling composition, process for its preparation, method to prevent fouling, method to turn a surface into an antifouling surface, and, covered surface
    Patent number: 8657943
    Abstract: 1-OH-2-acyl-sn-glycero-3-phosphocholine compounds and its analogs, pure or mixed, having formula WCH2CHXCH2PO3YCH2CH2Z, where W is preferably a hydroxyl group or an O-acyl group containing from 2 to 22 carbon atoms, and where X is preferably an O-acyl group containing from 2 to 22 carbon atoms or a hydroxyl (OH) and where Y may be an (O?) or OH and where Z is preferably a trimethyl-ammonium group [N+(CH3)3] can be protonated dimethyl ammonium [N+H(CH3)2] group. In the O-acyl groups containing 18 carbon atoms can be observed from 0 to 3 instaurations, useful as biocidal agents; processes for their preparation; and antifouling compositions, preferably paints useful in susceptible fouling surfaces, such as hulls of vessels. Methods to turn a surface into an antifouling surface, to a method to prevent fouling and to the antifouling surfaces comprising a coating of the said antifouling composition.

  • Substituted cumarines, process for the production of said cumarines and composition containing said cumarines
    Patent number: 7674398
    Abstract: Present invention refers to substituted cumarines that are capable to emit fluorescent light when illuminated by wave lengths within ultraviolet range. Present invention also refers to process of production of said substituted cumarines, well as provides compositions containing said substituted cumarines, especially compositions containing said cumarines and volatile solvents and/or adjuvants. Said compositions can be used in objects of great value for its owner, in view of facilitating the identification of such objects.

  • Hydrazines and derivatives production process from hydrazines and dicarboxylic acid
    Patent number: 7517983
    Abstract: The present invention describes a process to form hydrazides from the reaction of a hydrazine and a dicarboxylic, using a Lewis acid as a main reagent of the reaction. The reaction occurs in a safe reactional environment, utilizing smooth conditions, neither involving high temperatures nor high pressures, producing the desired products with high yields, between 90-95%. The invention also describes a kit for utilization of chemiluminescent substances, comprised of two solutions.
