Phosphorus Chlorides

PCl3 – Phosphorus Trichloride – is an important industrial chemical, used to manufacture organophosphorus compounds for a wide variety of applications, including herbicides, insecticides, plasticizers, oil additives, and flame retardants. Also used directly as a reagent in organic synthesis. It is used to convert primary and secondary alcohols into alkyl chlorides, or carboxylic acids into acyl chlorides.

POCl3 – Phosphorus OxychlorideIs an important industrial chemical, used to manufacture organophosphorus compounds for a wide variety of applications, including herbicides, insecticides, plasticizers, oil additives, and flame retardants. Also used directly as a reagent in organic synthesis. It is used to convert primary and secondary alcohols into alkyl chlorides, or carboxylic acids into acyl chlorides.

PCl5 – Phosphorus Pentachloride, used as a chlorinating reagent in the manufacturing of antibiotics. Also for the manufacturing of electrolytes for lithium ion batteries.

Phosphorus Pentasulphide

Lubricant additives: phosphorus pentasulphide is the key raw material in the production of the very important class of lubricant additives, zinc-dithio-phosphates (ZDDP).
Mining flotation agents: sodium, potassium, calcium or ammonium salts of dialkyldithiophosphoric acids are widely used as flotation promoters and collectors in mineral recovery processes.

Insecticides and Fungicides: A complete family of products synthesised from phosphorus pentasulphide is used as agricultural pest control agents. This family includes relatively non-toxic products, such as Malathion, and others, for example Parathion, of non-persistent, albeit high toxicity.

Acid Chlorides
Arese is one of the world’s largest producers of acid chlorides using the Phosphorus trichloride technology. A wide product range of distilled and undistilled (technical) acid chlorides of both natural and synthetic origin is regularly available.

 

Pharma
Several chemical intermediates manufactured by Italmatch Chemicals are used in the Pharma industry. PCl3POCl3 and PCl5 – are used as a chlorinating and sometimes also phosphorylating reagents in the manufacturing of pharmaceutical intermediates. Also to Fatty Acid Chlorides are used as intermediates in the manufacturing of API.

Vegetable Metallic Stearates are used in the pharmaceutical sector as lubricant coadjutants in tablet compacting, improving both the adherence and covering power.
