A procedure for the incorporation of sulfur into olefins which produces a non-staining, low odor, EP-active gear oil additive by reacting an olefin such as isobutylene with elemental sulfur in the presence of an aqueous solution of a strong base such as ammonia.

Sulfurized olefins

There is provided a process for reacting pentaerythritol with a trivalent phosphorus trihalide conducted in the presence of a phosphorus acid catalyst such as methyl acid phosphate. The reaction product is a useful intermediate for the preparation of flame retardants.

Phosphorus acid catalyst for preparation of

Phosphorochloridates and thionophosphorochloridates are stabilized against decomposition by the addition of minor amounts of phosphorus pentachloride or the equivalent minor amount of phosphorus trichloride and chlorine. Hydrogen chloride which may be formed is removed by sparging with inert gas. The invention permits the elimination of the customary expensive distillation step previously relied on for production of a stable product to attain commercially acceptable stability to alkyl phosphorochloridates such as diethylphosphorochloridate.

Stabilization of phosphorochloridates or thionophosphorochloridates with

This application is directed to a process for preparing dialkyl phosphoric acid, preferably di(2-ethylhexyl) phosphoric acid. This latter material is used in uranium extraction from wet-process phosphoric acid as a kerosine solution along with a synergist, trioctylphosphine oxide.

Process for the preparation of dialkyl phosphoric acids

A one step process for the preparation of phosphate esters of acidic hydroxy-containing compounds, e.g., phenols, by reacting said compounds with dimethyl disulfide and a trialkyl phosphite.

Selective phosphorylation process

A process for N-phosphorylating heterocyclic amines, e.g., pyrrole, comprising treating the amine with a complex formed by a mixture of bromotrichloromethane and a trialkyl phosphite.

Process for N-phosphorylation of heterocyclic amines

N-substituted carbamates derived from 5,8-dihydro-5,8-methano-1-naphthol and substituted derivatives therefor are new compounds having insecticidal activity. These tricyclic phenols are prepared, for example, by Diels-Alder condensation of cyclopentadiene with 2-cyclohexen-1-one (or substituted derivative), followed by dehydrogenation.

Carbamate insecticides from 5,8-dihydro-5,8-methano-1-naphthol and its

A one step process for the preparation of phosphate esters of phenol comprising reacting phenol with a dimethyl disulfide and a trialkyl phosphite.

1-Carbamoylvinyl phosphates and phosphonates are novel compounds which provide an effective means for controlling insects.
