Pigment preparations based on resin acid esters and aminoalcohols

Pigment preparations based on resin acid esters and aminoalcohols. Fournier, Pierre; Mayer, Jean (Produits Chimiques Ugine Kuhlmann, Fr.). Ger. Offen. DE 2704362 18 Aug 1977, 19 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C09D011-02. PRIORITY: FR 76-3040 4 Feb 1976. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Pigment prepns. with good rheol. properties, transparency, and tinctorial strength are prepd. by adding esters of amino alcs. with resin acids to aq. acidic suspensions of org. pigments and pptg. the esters with carboxylic or sulfonic acids or resin acids. Thus, 63.25 parts 3,3'-dichlorobenzidine is tetrazotized and coupled with 109 parts MeCOCH2CONHC6H3Me2 in the presence of 8.6 parts disproportionated rosin. An alc. soln. of 65.6 parts triethanolamine [102-71-6] ester of disproportionated rosin is added, the mixt. is stirred 15 min, combined with 21.8 parts heptanoic acid [111-14-8] in alk. soln., neutralized with soda, and heated 1 h at 80.degree. to give 230 parts yellow powder which, when added to a conventional binder, has better transparency and intensity than unmodified pigment.

Kairomones and their use for management of entomophagous insects

Kairomones and their use for management of entomophagous insects. XV. Identification of several acids in scales of Heliothis zea moths and comments on their possible role as kairomones for Trichogramma pretiosum. Gueldner, Richard C.; Nordlund, Donald A.; Lewis, W. Joe; Thean, James E.; Wilson, David M. (South. Grain Insects Res. Lab., ARS, Tifton, GA 31793, USA). J. Chem. Ecol., 10(2), 245-51 (English) 1984.In this article, certain chemicals are used. Some of their cas registry numbers are 88-14-2 and 99-96-7 CODEN: JCECD8. ISSN: 0098-0331. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Section cross-reference(s): 10 Acids found in scales of lab.-reared H. zea moths are hexanoic [142-62-1], heptanoic [111-14-8], octanoic [124-07-2], nonanoic [112-05-0], and 2- [88-14-2] or 3-furan carboxylic acid [488-93-7], as well as phenylacetic [103-82-2], benzoic [65-85-0], sorbic [110-44-1], and 4-hydroxybenzoic acid [99-96-7]. The last 2 acids are preservatives added to the artificial diet as sorbic acid and methyl-p-hydroxybenzoate [99-76-3]. Female T. pretiosum exhibited increased rates of parasitization of H. zea eggs in the presence of some of these compds. in lab. expts. Exposure to a mixt. of all of these compds. did not increase parasitization, and the elimination of acids from the crude moth-scale ext. did not reduce parasitization by the wasps. .
