Building material based on calcium sulfate a-hemihydrate

Building material based on calcium sulfate a-hemihydrate. Gradl, Reinhard; Heymer, Gero (Hoechst A.-G., Ger.). Ger. Offen. DE 2557594 30 Jun 1977, 12 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C04B011-14. APPLICATION: DE 75-2557594 20 Dec 1975. DOCUMENT TYPE: Patent CA Section: 58 (Cement and Concrete Products) An a-CaSO4.0.5H2O [26499-65-0] mix that is sufficiently fluid to form a level surface and harden quickly with good mech. strength is obtained by adding (iso-BuO)3PO [126-71-6], and a surfactant consisting of a C12-14 alkyl ether sulfate, Na N-methyl-N-(2-sulfoethyl)oleamide [137-20-2], a C16-18 olefin sulfonate, butylene glycol [25265-75-2], and H2O. In an example, setting occurred in 60 min, the floor could be walked upon after 3 h, and ultimate strength after 5 days was 108 kg/cm2.

Water-dispersible granular herbicidal compositions with increased thermal stability

Water-dispersible granular herbicidal compositions with increased thermal stability. Mookerjee, Pradip K.; Misselbrook, John (American Cyanamid Co. , USA). Eur. Pat. Appl. EP 112438 A1 4 Jul 1984, 28 pp. DESIGNATED STATES: R: AT, BE, CH, DE, FR, GB, IT, LI, NL, SE. (English). (European Patent Organization). CODEN: EPXXDW. CLASS: IC: A01N025-14; A01N033-18. APPLICATION: EP 83-108708 3 Sep 1983. PRIORITY: US 82-451140 20 Dec 1982. DOCUMENT TYPE: Patent CA Section: 5 (Agrochemical Bioregulators) A low melting substituted dinitroaniline I (where R1 = H, alkyl or alkenyl; R2 = alkyl, chloroalkyl, methoxyalkyl, alkenyl or alkynyl; R3 = H, Me, or CH3OCH2; R4 = alkyl, CF3, or Cl) 20-70%, a wetting agent 2-7.5%, a dispersing agent 2-6%, and a hydropholic or hydrophilic silica and swelling clay to 100% are admixed, cooled if heat was used, milled to a particle size of 5-100 mm, and granulated with water yielding the title product. Thus, sorptive silica (16.2 g) was heated to and agitated at 80°, and a blend (17.8 g) contg. N-(1-ethylpropyl)-2,6-dinitro-3,4-xylidene [40487-42-1] (the herbicide) 96.3%, Na dioctyl sulfosuccinate [577-11-7] 1.1%, and Et cellulose [9004-57-3] 2.6% is added with heat until the herbicide is adsorbed. The mixt. is then cooled to room temp. and blended with Na N-methyl-N-oleoyltaurate [137-20-2] 2 g, Na naphthalenesulfonate [1321-69-3] 2.0 g, and fumed silica 1.7 g. The compn. is then milled. Following storage at 50° for 24 h the compn. remained free flowing and dispersed well in water.
