Co naphthenate

Tracers. To a mixt of 34 parts of Laminae resin, 4 of benzyl ale, 2 of Co naphthenate, and 4 of me et ketone peroxide is added an equal wt of a mixt of 1 part of powd Mg and 2 of K perchlorate, The mixt is formed and cured to give a tracer for following visibly the path of rockets (Ref 24). In Ref 16, p 275 are given formulations for mixts contg K perchlorate which is used in tracer ammo for automatic small arms. Tracer compns contg powd Zr which are suitable for modem HV small arms are discussed in Ref 30...

Monofunctional p-isopropenylphenyl cyanate was used with BPA/DC in a composition with BPA diglycidyl ether and Co naphthenate catalyst [80],... 

The cyanate and the epoxide network can be bound by the reaction of phenolic hydroxyls contained in the partially cyclotrimerized cyanate prepolymer with the epoxy groups. In the first stage, a prepolymer was obtained by heating a mixture of BPA monocyanate and dicyanate with Co naphthenate as a catalyst (Scheme 15).

Results obtained with catalysts based either on ethanolic CoCl2 or on Co-naphthenate do not differ much, as comparing Figure 6 with Figure 7 and Figure 5 with Figure 8 will show. Apparently the minute amount of ethanolic CoCl2 does not disturb the polymerization activity. 

Lactams and amides are easily oxidized to imides with hydroperoxides in the presence of Mn(acac)2 or Co" naphthenate. For example, 2-piperidone is oxidized to glutarimide in 72% yield using Mn(acac)2. 

Other metal species, which are known to be active in aerobic radical reactions such as vanadium compounds [83], Co naphthenate [84], CoJacetateJj [85], Co oleate [86], and metal porphyrins [87], were also reported to give low yields of AA with molecular oxygen. When the aerobic scission of olive oil fatty acids in a ball mill in the presence of Ce02 stopped at the aldehyde stage, 9-oxononanoic acid and nonanal besides a range of other aldehydes were received [88]. 

Lee et used the ebullated-bed reactor for catalyst preparation from AC and soluble metal precursors. In their study, the oil-soluble Mo and Co naphthenates were introduced with an AR into the continuous ebullated bed of AC granules (623 K and 6.9 MPa of H2). The co-dispersed catalyst exhibited high activity for HDS, HDM and HDAs at the optimal Co/(Co + Mo) ratio of 0.3. However, the HCR activity of the Mo/AC catalyst was greater than that of the CoMo/AC catalyst.
