Thus, a catalyst system comprising Et3Al 5, Al-activated TiCl3 2.5, and 2,6-lutidine-N-oxide (I) [1073-23-0] 2 mmol was added to 190 mL hexane (II) and reacted with propylene 1-4 h at 25.degree. and 40 psig to give a cryst. polypropylene [9003-07-0] at catalyst activity of 27.5 g/g TiCl3/h and II-solubles of 13.2% as compared with 26 and 32.7, resp., when no I was used. .

CODEN: FAVUAI. ISSN: 0533-1153. DOCUMENT TYPE: Journal; General Review CA Section: 5 (Agrochemical Bioregulators) Section cross-reference(s): 4 Anal. of published data indicates that in specific tests ivin (2,6-lutidine) [90881-19-9] shows a weak auxin and cytokinin activity. Ivin acts on whole plants in a manner resembling auxins, gibberellins, and cytokinins. Seed soaking and spraying ivin stimulates initial growth, slightly hastens the onset of flowering and fruiting, and increases the early and total yield of cucumber, tomatoes, potatoes, and cotton. Acute oral LD50 values of ivin were 1390 and 1645 mg/kg for mice and rats, resp. .
