The highest tin recovery was achieved using collector / -tolyl arsonic acid. Based on laboratory data, a small plant was designed where ethyl phenyl phosphonic acid was used as collector at 450 g/t additions. Depressant used included 1000g/tNa2Si03 and 1000 g/t NaF. The plant results are shown in Table 21.9.

The synthesis of multidentate Lewis acids is of great interest [102]. The photostimulated reactions of [o-(diethoxy-phosphoryl)-phenyl]-phosphonic acid diethyl ester with Me3Sn- ions in liquid ammonia affords the disubstitution product 6>-Z f -trimethylstannanyl-benzene 29a in 67% yield [103]. Under the same experimental conditions, 2,2/-Zus(diethylphosphoxy)-1,1 -binaphthyl 30 affords the disubstitution product 31 in high yields (Sch. 28) [103].

Three groups of plasticizing rotonating agents have been used in the preparation of a conductive composite of PANI and cellulose acetate sulfonic acids, phosphonic acids (phenyl phosphonic acid), and aliphatic diesters of phosphoric acid (dipheityl, dioctyl and dibutyl). These plasticizers improved the flexibility of the film but also significantly lowered the percolation threshold. The addition of plasticizer improves the dispersion of PANI in cellulose acetate. In this and other inventions based on the composite polymer it has been foimd to be important that the plasticizer not only helps to dissolve or soften PANI but also plasticizes the matrix polymer. In some inventions, a combination of plasticizers has been used. For example dodecylbenzenesulfonic add acted as a doping... 

Aromatic polymers with phosphonated sites directly linked to the main chain have also been prepared by direct polymerization (Scheme 13.2a-d). For example, phosphonated poly(l,3,4-oxadiazole)s have been prepared by direct polycondensation of l,4-dicarbo3y-2-phenyl-phosphonic acid and their dihydrazides in an ionic liquid using triphenyl phosphite as a reaction activator. " The membranes obtained from these polymers were thermally and chemically stable and possessed proton conductivities in the range between 4x10 " and 5x10 mS cm at 100% RH, which is three orders of magnitude lower than the state-of-the-art PFSA membrane Nation .
