Abstract

Glufosinato Sólido Solúvel para Defensivo Agrícola, Processo para sua Obtenção e Processo de Controle de Pragas Agricolas. A presente invenção descreve defensivos agrícolas compreendendo glufosinato sólido seco e solúvel em água, bem como o processo para sua produção. O produto da invenção compreende sal de amônio de glufosinato, em elevados teores de pureza (95 a 100% de pureza) e baixo teor de umidade <1,0% m/m. O processo de produção tem como princípio a reação em um sistema sólido/liquido/sólido entre um sal de amônio sólido e o glufosinato ácido sólido dispersos em um meio orgánico liquido não aquoso. O produto desta reação possui adequada solubilidade em água e pode ser utilizado diretamente como defensivo agricola ou como ingrediente na preparação de composições de contendo sais de glufosinato em várias combinações de adjuvantes. O processo de produção da invenção apresenta, entre outras, as seguintes vantagens sobre os congêneres conhecidos: requer menos investimentos para as instalações industriais; os custos de operação são inferiores, a segurança para os operadores é maior; o processo de produção é ambientalmente melhorado, uma vez que os insumos utilizados, além de menos tóxicos ao ambiente, são reutilizáveis e ou recicláveis. Além disso, o processo da invenção não acarreta o problema técnico da formação de calor, e o produto da invenção compreende o sal de amônio de glufosinato na forma sólida e com alto teor de pureza. Como o produto da invenção contém baixa concentração de água, reduz substancialmente os problemas técnicos e custos envolvidos no seu transporte.Soluble Solid Glufosinate for Agricultural Defensive, Process for Obtaining and Process of Agricultural Pest Control. The present invention describes agricultural pesticides comprising dry and water-soluble solid glufosinate as well as the process for their production. The product of the invention comprises glufosinate ammonium salt, in high purity (95 to 100% purity) and low moisture content <1.0% w / w. The production process is based on the reaction in a solid / liquid / solid system between a solid ammonium salt and solid acid glufosinate dispersed in a non-aqueous liquid organic medium. The product of this reaction has adequate water solubility and can be used directly as a pesticide or as an ingredient in the preparation of glufosinate salt-containing compositions in various adjuvant combinations. The production process of the invention has, among others, the following advantages over known counterparts: requires less investment for industrial facilities; Operating costs are lower, safety for operators is higher; The production process is environmentally improved, as the inputs used, besides being less toxic to the environment, are reusable and or recyclable. Furthermore, the process of the invention does not entail the technical problem of heat formation, and the product of the invention comprises the high purity solid form glufosinate ammonium salt. As the product of the invention contains low water concentration, it substantially reduces the technical problems and costs involved in its transportation.
