Usage

General Description

The chemical [(phenylmethyl)imino]bis(methylene)]bisphosphonic acid is a type of organophosphorus compound that is commonly used as a chelating agent and corrosion inhibitor. It has two phosphonic acid groups, each attached to a methylene group, and a nitrogen atom coordinated to the two methylene groups. [(phenylmethyl)imino]bis(methylene)]bisphosphonic acid is often used in industrial water treatment to prevent scale formation and corrosion in boilers and cooling systems. It is also used in the formulation of detergents and cleaning products to effectively remove calcium and magnesium ions from hard water. Additionally, [(phenylmethyl)imino]bis(methylene)]bisphosphonic acid has potential biomedical applications as a bone resorption inhibitor for the treatment of osteoporosis and other bone disorders.

A phosphonate coordination polymer with highly sensitive detection of ascorbic acid and the proton conductivity of its polymer composites

A phosphonate coordination polymer, [Cd(H3bmpa)2]n (1), based on Cd2+ ions and H4bmpa (H4bmpa = N-Benzyliminobis(methylenephosphonicacid)) was synthesized under hydrothermal conditions. It is characterized by single crystal X-ray diffraction, PXRD and TGA. Crystal structure indicates that adjacent Cd2+ ions are linked by oxygen atoms in the phosphonate groups to form a 1D chain structure. Adjacent 1D chains are further linked by hydrogen bonds to form a 2D planar structure. Complex 1 is a bifunctional material that has both fluorescent and proton conducting properties. It can detect ascorbic acid sensitively and selectively with a detection limit of 5 μM. To further improve the proton conductivity of Complex 1, PVA (Polyvinyl alcohol) was introduced with it to prepare the composites. The proton conductivity of 1?PVA-10 is 3.05 × 10?5 S·cm?1 (323 K, 98% RH), which is two orders of magnitude higher than that of coordination polymer.

Benzylamine-N,N-dimethylene phosphonate melamine salt and preparation method and application thereof

The invention discloses a benzylamine-N,N-dimethylene phosphonate melamine salt and a preparation method and application thereof. A reaction ratio, by a molar ratio, of benzylamine-N,N-dimethylene phosphonic acid to melamine is 1.0:1.0-5.0, and the benzylamine-N,N-dimethylene phosphonic acid is prepared by reaction of benzylamine, formaldehyde and phosphorous acid according to a molar ratio of 0.5-1.5:1.0-5.0:1.0-5.0. The preparation method includes: respectively adding the benzylamine, the formaldehyde and the phosphorous acid, reacting, heating, refluxing, and respectively washing with dilute acid and water after reaction is finished, so that the benzylamine-N,N-dimethylene phosphonic acid is obtained; adding the benzylamine-N,N-dimethylene phosphonic acid and the melamine, then adding the deionized water and N,N-dimethylformamide, stirring, refluxing, cooling obtained products in ice-water bath after reaction is finished, carrying out suction filtration, washing with water, and drying to obtain white solid which is the benzylamine-N,N-dimethylene phosphonate melamine salt. The benzylamine-N,N-dimethylene phosphonate melamine salt has advantages of low smoke, low toxicity, freeness of corrosive gas, environment friendliness, high efficiency and the like and accords with the future flame retardant research and development direction.

Synthesis of bis- and tris-organophosphorus substituted amines and amino acids with PCH2N Fragments

The aminomethylation of the derivatives of trivalent organophosphorus acids, containing PH and POSiMe3 fragments with various bis- and tris(alkoxymethyl)amines and bis(alkoxymethyl)amino acids, is proposed as a convenient method for the synthesis of new bis- and trisphosphorylated amines and amino acids as well as their derivatives with four and five coordinated phosphorus. Also the three-components systems of phosphorous acid, paraformaldehyde, and amines are thoroughly investigated via the treatment of reaction mixtures with bis(trimethylsilyl)amine.
