Phosphoric ester metal salt

A phosphoric ester metal salt nucleating agent which is easily dispersible in a crystalline polymer and effective in improving transparency and mechanical strength of the crystalline polymer is used in wire coating material. ... 

Polypropylene blown film which has excellent optical and mechanical properties was obtained using nucleating agents. The polypropylene composition contains a clarifier selected from the group of aromatic phosphoric acid ester metal salts and almniniitm-hydroxy-bis[2,2 -methylene-bis(4,6-di-t-butylphenyl)phosphate] in the qirantities from 0.01 to 5 wt%. ... 

The crystalline nucleating agent for polyolefin resin composition for bottle production comprises l,3 2,4-bis(3, 4 -dimethylbenzylidene) sorbitol and a phosphoric acid ester metal salt compoimd. ... 

Phosphorus containing additives include esters of phosphoric acids, derivatives of thiophosphoric acids, phosphites (Davey, 1950 Sakuri and Sato, 1970), and the metal salts of dithiophosphoric acid diesters, the best known of these compounds being the ZDDPs. The structure of ZDDP films, the composition of the film formed, and the mechanism of action on the molecular level are summarized in Chapter 4. 

Phosphorus oxychloride is a suitable reagent for preparation of the symmetrically substituted phospho-triesters of type (RO)3PO. The preparation is easily achieved by treatment of phosphorus oxychloride with 3 equiv. of alcohols or their metal salts. The reaction is generally promoted by a base or acid. Titanium trichloride is a particularly effective catalyst for the reaction. Conversion of POCI3 to unsymmetri-cally substituted phosphotriesters is achievable with difficulty. Phosphorochloridates and phosphorodichloridates have been used for the preparation of mixed tertiary phosphoric esters of type (ROlmPOfOROn (ffi = 1, n = 2, or m = 2, n = 1) in a very wide variety. Reaction of phosphorus oxychloride and 1 or 2 equiv. of alcohols followed by hydrolysis forms phosphomonoesters or phosphodi-esters, respectively. The hydrolysis may be generally effected by dilute aqueous alkali. Some phosphoFodichlori te intermediates are easily hydrolyzed by water. For example, the phosphorylation of a ribonucleoside (1 equation 4) with phosphorus oxychloride in an aqueous pyridine-acetonitrile mixture furnishes the nucleoside S -monophosphate (2) in excellent yield. ... 

Soaps, metallic salts of organic acids, esters of phosphoric and phosphinic acids, organotin compounds, chelate and certain other substances are customarily used to increase the activity of epoxide stabilizers [24, 63, 265]. 

As has already been mentioned in the discussion of metallic salts of organic and inorganic acids, the acid radicals of such stabilizers can represent esters of phosphoric or alkylphosphinic acids. In addition to salts of alkylphosphinic acids, the use of sodium, aluminum, barium, and calcium salts of aliphatic esters of phosphoric acid is recommended [291].

Treating petroleum oils with 3-5% calcium alkyl salicylate and 0.5-3% triethanolamine salts of phosphoric acid esters and ethoxylated dodecyl alcohol increases oxidation-thermal stability at 180-200°C in the manufacture of oil for metal parts quenching. The agent provides also short-term anticorrosion protection of the hardened articles [261]. Phosphoric acid salt alkyl esters are used in anticorrosives and aqueous dispersions in waterborne polyester coatings for metals [244]. 

In 2004, List reported that several ammonium salts including dibenzylammonium trifluoroacetate catalyzed the chemoselective 1,4 reduction of a, 5-unsaturated aldehydes with Hantszch esters as hydride sources [40]. It is assumed that substrate activation via iminium ion formation results in selective 1,4 addition of hydride. Subsequently, List [41] and MacMillan [42] reported asymmetric versions of this reaction promoted by chiral imidazoUdinone salts. In this context, several reports of this metal-free reductive process catalyzed by chiral phosphoric acids have appeared in the recent literature. 

Catalytic activity of rare earth elements (i.e., lanthanides, symbol Ln) in homogeneous catalysis was mentioned as early as 1922 when CeCls was tested as a true catalyst for the preparation of diethylacetal from ethanol and acetaldehyde [1]. Solutions of inorganic Ln salts were subsequently reported to catalyze the hydrolysis of carbon and phosphorous acid esters [2], the decarboxylation of acids [3], and the formation of 4-substituted 2,6-dimethylpyrimidines from acetonitrile and secondary amines [4]. In the meantime, the efficiency of rare earth metals in heterogeneous catalysis, e. g., as promoters in lanthanide (element mixtures)-...

However, this can now be overcome through the use of a cool-on-line injector and programming of the oven after sample injection (P. Teal, personal comm.). Cyclization of JH III to mono- and bicyclic products also occurs readily in the presence of boron trifluoride or phosphoric acid (H3PO4) [34]. Transition metals may catalyze similar reactions in aqueous solutions [12]. Inorganic salts, such as ferric chloride and zinc and magnesium sulfate, react with JH I, producing undetermined products [35]. The methyl ester function on C-l of JH III is resistant to saponification by strong base [14].
