Oil Toxicity

Hydrocarbon oils of varying boiling range and percentage "aromatic" fraction were tested for their toxicity to Paspalum dilatatum in the field and glass-house.Contact injury and final toxicity are separate phenomena and are controlled by different factors. The contact effect of oil herbicides depended on the proportion of aromatic fraction in the oil. The minimum percentage of aromatics required to produce rapid contact injury increases with increasing boiling-point of the oil. Mid boiling-point was shown to be an important and consistent factor in oil toxicity as measured by regrowth. Oil toxicity increases with mid boiling point of the oil. Toxicity in the field decreases with increasing aromatics. In the glasshouse the reverse is the case.

Time Required

AbstractBoth the vapour and particulate phases of tobacco smoke have been shown to retard benzoyI-peroxide-initiated polymerisation of vinyl acetate by interception of the radicals involved in the polymerisation process. The extent of inhibition of polymerisation by test compounds is estimated by measuring time taken for a mixture of monomer and benzoyl peroxide, immersed in a water-bath at 70°C, to reach a spontaneous boil and comparing it with the time required for a similar mixture with added retarder to reach boiling point. Units are expressed as minutes of inhibition per part per million of inhibitor × 10

Abstract HASTELLOY ALLOY-D is a cast alloy composed primarily of nickel and silicon, and is exceptionally resistant to sulfuric acid of all concentrations even up to the boiling point. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Ni-29. Producer or source: Haynes Stellite Company.
