DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Section cross-reference(s): 23 Co 2-ethylhexanoate (I) [136-52-7] drier for polyesters is manufd. from aq. Na 2-ethylhexanoate [19766-89-3] and Co(NO3)2 at pH 6-6.5 and 65-75° in the presence of nonpolar solvents, e.In this article, certain chemicals are used. Some of their cas registry numbers are 71-36-3 and 104-76-7 g., extn. gasoline, and deflocculants, e.g. BuOH [71-36-3] or 2-ethylhexanol (II) [104-76-7]. 35 G water contg. 35 g 2-ethylhexanoic acid was sapon. 1-1.5 h at 70-75° with 14-16% aq. NaOH. Thus, heating the Na salt of 35 g 2-ethylhexanoic acid in 35 g H2O with 133 g 14% Co(NO3)2 for 30 min at 65° in the presence of 15 g extn. gasoline and 5.6 g II gave I. .

Microencapsulated aqueous polymerization catalyst

Microencapsulated aqueous polymerization catalyst. Henderson, James N.; Donbar, Ken W.; Barbour, John J.Several substances are used for example 75-15-0 and 58783-82-7 which are their cas registry numbers.; Bell, Anthony J.

APPLICATION: US 82-419261 17 Sep 1982. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) Syndiotactic 1,2-polybutadiene (I) [31567-90-5] is manufd. in an aq. medium by polymn. of butadiene (II) [106-99-0] in presence of CS2 and a catalyst contg. AlR3 (R = C1-6 hydrocarbyl) and Co compd. selected from the group consisting of b-diketone complexes, b-keto acid ester complexes, salts of carboxylic acids having 6-15 carbon atoms, and complexes of halogenated Co compds., wherein the catalyst compns. are microencapsulated in a polyene product. A catalyst component soln. was prepd. by mixing 22.5 mL of a 1.85 M II in hexane with 5.53 mL of a 1.52 M AlEt3 [97-93-8] soln. in hexane and 1.74 mL of a 0.96 M cobalt octoate [136-52-7] soln. in mineral spirits and shaking 1 h at room temp. in a capped bottle. A mixt. consisting of 0.58 mL catalyst component, 40 g deionized water, 20 g II, and 0.49 mL 0.10 M CS2 soln. in hexane was placed in a bottle and tumbled 22 hs at 10°. The resulting polymer was soaked in a 1% soln. of 2,6-di-tert-butyl-p-cresol in MeOH, washed 2 times with the MeOH soln., filtered, and vacuum dryed at 90° to give I in 38% yield, with peak melting temp. 188°. Addn. of 5-tridecanol [58783-82-7] to the catalyst mixt. gave I in 63% yield with m.p. 164°. .
