N-cyclohexyl-1-chlorophthalimlde (250 g) was dissolved in glacial acetic acid (2.5 8),concentrated hydrochloric acid (555 ml) and tin (27B g) were added and the suspension was heated on a steam bath for 16 hours. The cooled solution was filtered and concentrated to dryness in vacuo to give a white solid. This solid was dissolved in water and the precipitated oil extracted with chloroform. The chloroform solution was dried and concentrated in vacuo to give a solid which, after recrystal I izat ion, yielded 5-chloro-2-cyclohexylisoindolin-1-one (43%), MP 140°Cto 142°C.

Geminale Chlor-nitroso-Verbindungen werden durch Lithiumalanat in Diathylather (40-70% d.Th.) oder besser mit Natriumboranat in waBrigem Athanol (50-80% d.Th.) zu Oximen reduziert. Als Nebenprodukte konnen gelegentlich Hydroxylamine isoliert werden. So erhalt man z.B. aus 1-Chlor-l-nitroso-cyclohexan mit Natriumboranat neben 61 % d.Th. Cyclohexanon-oxim 11 % d.Th.V-Cyclohexyl-hydroxylamin5. Dagegen werden bei der Reduktion von 1-Nitroso-l-acetoxy-cyclohexan Cydohexanol (8% d.Th.) und N-Cyclohexyl-acetamid (34% d.Th.) erhalten6.

Now, the dream has become a reality. Figure 19.5 shows 3D-TEM images of three NR vulcanizates, cured by sulfur/N-cyclohexyl-2-benzothiazolyl-sulfenamide (CBS) curing system, CB-10, CB-40, and CB-80 containing 10, 40, and 80 phr high-abrasion furnace (HAF) carbon black. In the black and white images the contrast was reversed, and the white is identified as the carbon black. Association to aggregates is observed even in CB-10 (volume fraction is 0.0498).

Sulfonated styrene-maleimide copolymers are similarly active [1073], Examples of maleimide monomers are maleimide, N-phenyl maleimide, N-ethyl maleimide, N-(2-chloropropyl) maleimide, and N-cyclohexyl maleimide. N-aryl and substituted aryl maleimide monomers are preferred. The polymers are obtained by free radical polymerization in solution, in bulk, or by suspension. 

Applications Identification of polymer additives by TLC-IR is labour intensive and comprises extraction, concentration of extracts, component separation by TLC on silica, drying, removal of spots, preparation of KBr pellets and IR analysis. The method was illustrated with natural rubber formulations, where N-cyclohexyl-2-benzothiazyl sulfenamide, IPPD and 6PPD antioxidants, and a naphthenic plasticiser were readily quantified [765]. An overview of polymer/additive type compounds analysed by transfer TLC-FTIR is given in Table 7.80.
