Exempel på hur man kan använda CYANAMIDE i en mening

• Schulze and Winterstein synthesized arginine from ornithine and cyanamide in 1899, but some doubts about arginine's structure lingered until Sørensen's synthesis of 1910.
• Like cyanamide, it contains 66% nitrogen by mass, and its derivatives have fire-retardant properties due to its release of nitrogen gas when burned or charred.
• Thiourea can be produced from ammonium thiocyanate, but more commonly it is manufactured by the reaction of hydrogen sulfide with calcium cyanamide in the presence of carbon dioxide.
• In contact with water, it hydrolyses into hydrogen cyanamide which decomposes and liberates ammonia:.
• One process starts with a reaction of methyl chloroformate with cyanamide, forming hexazinone after a five-step pathway:.
• Water, hydrogen sulfide, and hydrogen selenide react with cyanamide to give urea, thiourea, and selenourea, respectively:.
• Symmetrical 1,3,5-triazines are prepared by trimerization of certain nitriles such as cyanogen chloride or cyanamide.
• With calcium cyanamide and calcium nitrate (made from nitric acid), Lonza commercialised formulated fertilisers starting in the 1930s.
• The recent patent literature describes the synthesis of glycocyamine by catalytic oxidation of ethanolamine to glycine and subsequent reaction with cyanamide in aqueous solution in high yield, analogous to the synthesis of creatine starting from 2-methylaminoethanol via sarcosine.
• Instead of assembling the nucleotide components in stepwise linear reactions, the synthesis proceeds through the reaction of cyanoacetylene with an aminooxazole intermediate that is formed from glycolaldehyde and cyanamide, molecules that were likely present on early Earth.
• In a more efficient and controllable one-pot synthesis, cyanamide is treated with hydrazine hydrochloride to give aminoguanidine hydrochloride, which is then diazotized as in Thiele's original process.
