dicyanamideの例文

• Although named as a dicyanamide, the major organic structure is a 2-cyanoguanidino group.
• A co-worker then considered this reactive nature and examined the possible role dicyanamide may have had in primordial biogenesis.
• Sodium dicyanamide is available in good yield and high purity from cyanamid and cyanogen chloride, which is suitable as an intermediate for the synthesis of active pharmaceutical ingredients.
• "' Methylmercuric dicyanamide "'is a chemical compound used as a fungicide for crops such as cereals, cotton, flax, sorghum, and sugar beets.
• Loss of ammonia ( NH 3 ) from the zwitterionic form, followed by deprotonation of the remaining central nitrogen atom, gives the dicyanamide anion, [ N ( CN ) 2 ]  ".
• The burn rate modifiers in the mixture may be an alkaline metal nitrate ( NO 3-) or nitrite ( NO 2-), dicyanamide or its salts, sodium borohydride ( NaBH 4 ), etc . The coolants and slag formers may be e . g . clay, silica, alumina, glass, etc . Other alternatives are e . g . nitrocellulose based propellants ( which have high gas yield but bad storage stability, and their oxygen balance requires secondary oxidation of the reaction products to avoid buildup of carbon monoxide ), or high-oxygen nitrogen-free organic compounds with inorganic oxidizers ( e . g ., di or tricarboxylic acids with chlorates ( ClO 3-) or perchlorates ( ClO 4-) and eventually metallic oxides; the nitrogen-free formulation avoids formation of toxic nitrogen oxides ).
