  The cyclic ether bis-phosphonic acids diphosphonotetrahydrofuran, diphosphonotetrahydropyran, and diphosphonooxepane and their salts and esters are disclosed, as is their use in water treatment. Also disclosed is the preparation of the cyclic ether bis-phosphonic acid compounds by reacting a corresponding dialkoxy cyclic ether with certain dialkyl phosphites, reacting the intermediate formed therefrom with certain halotrimethyl silanes, organic acid halides or inorganic acid halides, and reacting the intermediate formed therefrom with certain trialkyl phosphites to form a bis-phosphonic acid compound which may be hydrolized to form the cyclic ether bis-phosphonic acid. Certain of the first intermediates are considered stable reagents which may be used for preparing flame retardants, chelating agents and corrosion inhibitors.

  本发明公开了环醚双膦酸二膦酰基四氢呋喃、二膦酰基四氢吡喃和二膦酰基氧杂环庚烷及其盐和酯，以及它们在水处理中的用途。还公开了环醚双膦酸化合物的制备方法，即相应的二烷氧基环醚与某些二烷基亚磷酸反应，由此形成的中间体与某些卤代三甲基硅烷、有机酸卤化物或无机酸卤化物反应，以及由此形成的中间体与某些三烷基亚磷酸反应形成双膦酸化合物，该化合物可水解形成环醚双膦酸。某些第一种中间体被认为是稳定的试剂，可用于制备阻燃剂、螯合剂和缓蚀剂。
