Abstract: Nitrogen-containing 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide derivatives are prepared by condensation of the oxide with amines and aldehydes or ketones. They may be used as additive flame retardants or incorporated into synthetic resins such as polyesters and polyurethane foams, by copolymerization to form flame-retardant resins. They may also be used as antioxidants, germicides or herbicides.

Abstract: The compound (phosphonomethyl)perfluoroalkyl sulfonate can be represented by the formula ##STR1## wherein n is from 0 to 7 and R and R.sup.1 are independently selected from the group consisting of hydrogen, 2-cyanoethyl, monovalent hydrocarbons containing from 1 to 18 carbons, monovalent hydrocarbonoxyhydrocarbons containing from 1 to 18 carbons, halogenated monovalent hydrocarbons containing from 1 to 18 carbons and from 1 to 3 halogens, halogenated monovalent hydrocarbonoxyhydrocarbons containing from 1 to 18 carbons and from 1 to 3 halogens. The compound is useful as an intermediate to prepare amino-phosphorous compounds such as N-phosphonomethylglycine.

Abstract: Antistatic agents for synthetic fibers comprising a specific type of quaternary ammonium alkyl phosphate as principal constituent and 1 weight percent or less of by-product alkali metal halides have improved antistatic characteristics both in high and low humidity conditions and reduce the amount of deposits that fall off, yellowing by a heat treatment and generation of rust. Methods of producing such antistatic agents are also disclosed.

Abstract: One-step process for preparing anhydrous, organic acid alkali or alkaline earth metal salts by contacting and reacting an organic or polymeric acid fluoride, anhydride or ester and an organic alkali or alkaline earth metal silanolate.

Abstract: A process for the preparation of phosphorus-containing .alpha.-amino nitriles of the general formula I ##STR1## in which R.sub.1 and R.sub.2 denote (substituted) alkyl, aryl, aralkyl or cycloalkyl, R.sub.3 denotes H, alkyl, phenalkyl, acyl, alkoxycarbonyl or aryloxycarbonyl, and n denotes zero or one, by reaction of corresponding acylals with alkali metal cyanides under the conditions of the Strecker synthesis.

Abstract: A process for the preparation of phosphate compounds comprising (1) reacting an inorganic phosphate salt with epihalohydrin to obtain a phosphate ester and (2) reacting the phosphate ester with a substituted amine wherein step (1) is carried out at a pH of from about 5.4 to 7.0.

Abstract: A process for making an organicammonium dialkyl phosphorodithioate has been discovered which involves a critical order of reactant addition. Thus it is essential to the process that the amine be added to a mixture of phosphonate and elemental sulfur.

Abstract: Novel guanidated aminophosphonic acid compounds their use as biocides and their intermediates. The compounds are guanidated N-(aminoalkyl) aminoalkanephosphonic acid derivatives and are characterized in that they comprise both a phosphonic acid type group and at least one guanidino group and also in that they are based on alkylene amines. The compounds have the general formula: ##STR1## wherein Z and Z' are hydrogen, a lower alkyl group or an alkali metal, Y is hydrogen or an amidine group, m is 1-3, n is 4-16 and p is 1-3. The compounds can be prepared by reacting a halogenoalkanephosphonic acid compound with an alkylene di- or polyamine followed by guanidation of the so obtained product. The compounds are particularly useful as fungicides and especially as fungicides for industrial purposes.

Abstract: Disclosed are novel 5-halo-4H-1,3-dioxin-4-ones and their preparation by treating a compound having the formula ##STR1## with X.sub.2 or SO.sub.2 X.sub.2 wherein X is Cl or Br.

Abstract: The invention relates to new organic phosphoric acid esters represented by the general formula ##STR1## wherein X represents O, S or NH,Y represents O or S,R.sup.1 represents a lower alkyl group,R.sup.2 represents a lower alkyl group or a lower alkoxy-lower alkyl group,R.sup.3 represents a fluoro-substituted lower alkyl group,Z represents a lower alkyl group, a lower alkoxy group or a halogen atom, andn represents 0 or 2,which can be used as pesticidally active agents.
