However, although phosphate groups provide highly effective dispersion in cementitious systems, they have a major environmental disadvantage due to formaldehyde and non-biodegradable phenolethoxylate used in its synthesis [19,36]. The binding of phosphonate and phosphate groups with Ca2+ is more complex...
-1- ABSTRACT Phosphate esters having the formulawherein A has the structural formulaand B has the structural formulawherein the R groups are alkyl radicals, m and n are each integers from 0 to 4 and the sum of m + n is from 1 to about 4, are useful as flame retardants, especially ...
Phosphate plays a critical role in the formation and maintenance of bones andteeth. It combines with calcium to form hydroxyapatite, themineralthat gives bones and teeth their strength and rigidity.Fluoroapatite,a type of hydroxy calcium phosphate in which some hydroxyl groups are“substituted with f...
NAPHTHOL AS-BI PHOSPHATE, with the chemical formula C20H14O8P and CAS registry number 1919-91-1, is a compound known for its applications as a dye and colorant. This compound, also referred to as Naphthol AS-BI Phosphate, is characterized by its naphthol and phosphate functional groups. It...
Phosphate ion is a polyatomic ion with the formula PO43−. A phosphate functional group, though related in composition to the phosphate ion, would have to have something else bonded to one of the oxygens in the phosphate function group....
ChEBI: A trialkyl phosphate that is the tributyl ester of phosphoric acid. 3.2 Description Tributyl phosphate (CAS 126-73-8) is a colorless to pale yellow liquid with a fruity odor. It has the chemical formula (C4H9O)3PO and consists of three butyl groups attached to a phosphate group. ...
KDP belongs to the class4¯2m of the tetragonal system with the space group I4¯2d. The unit cell dimensions area=b=7.434Å andc=6.945Å. There are four formula units per cell. The structure is most easily pictured as built up from potassium atoms and phosphate groups as shown inF...
Due to the nature of this approach, it is capable of combining individual pathways into larger, more complex groups of metabolic pathways. Averaging the results from several simulation runs provides information on the average changes in the concentrations of the individual pathway metabolites. The ...
Dibutyl phosphate, with the chemical formula (C4H9O)3PO and CAS registry number 107-66-4, is a compound known for its role as a solvent and plasticizer. This colorless liquid is characterized by its phosphate group attached to the butyl groups. It is commonly used in the production of ...
with the evolution of volatile phosphine oxides, which then act in the vapour phase and retard the burning polyester component. Dayet al.3have also provided evidence that the flame retarding efficiency of now-banned tris(2,3-dibromopropyl) phosphate or ‘tris’, when applied to polyester, is ...
