Phosphonium Chlorides Offer Several Advantages

Making them a popular interest area for researchers to find new applications

Tetraalkylphosphonium chlorides are readily available on a large scale and currently offered by the Strem Catalog in collaboration with Solvay.


This compilation provides easy access to the key information about these products, including technical notes about the applications and the references which pertain to a particular molecule. Besides the references presented on the Strem Catalog website, it is worthwhile to mention some other key publications.

A number of years ago a series of phosphonium chlorides were prepared from both trioctylphosphine [1] and tributylphosphine [2] and the respective 1-chloroalkanes, CnH2n+1Cl (where n = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12 or 14). In these publications, the authors systematically studied the properties of the phosphonium chlorides focusing on understanding how n impacts the physical properties such as melting points/glass transition temperatures, thermal stability, density, and viscosity. This information may prove useful for researchers in both academia and industry.

Phosphonium chlorides are amenable to the anion exchange (metathesis) reaction producing an enormous number of new molecules and this well-known aspect is not reviewed here.
