U.S. production of titanium dioxide in 1993 was 1.16 x 10 t, an increase of about 2.2% over 1992 (15). The annual production increased on an average of 5.4% in the 1980s (16). There are approximately 50 world producers of titanium dioxide pigments. The world s leading suppHers are Du Pont (- 24% worldwide share), Tioxide (the U.K. Co. owned by ICI), and SCM Corp. Other producers include Kerr McGee, Tiwest, Kemira Oy, Kronos, and Bayer AG (see Titanium compounds, inorganic).

N-BOC thiazolidines can be cleaved with ScmCl (methoxycarbonyl-sulfenvl chloride) (AcOH, DMF, HoO) to afford the Scm derivative in >90% yield. ... 

These conditions convert the Acm group to a methyl 5-sulfenylthiocarbon-ate group (Scm group), which can be cleaved with dithiothreitol. ... 

A 0.2 mol L"1 LiCl/THF solution possesses only very low conductivity of 1.6xl0"6 Scm"1. Addition of N(CH2 CH2NR2)3(R = CF3S02 short nomenclature M6R) yields an increase in conductivity by three orders of magnitude to 1.7 x 10 3 S cm"1. This approach is seemingly especially useful for battery electrolytes, because the transference number of the lithium ion is increased. Conceptually this approach is similar to the use of lith-...
