the product obtained after stripping was a very light tan clear semi solid which showed an intense nco band in the ir spectrum at 2250 cm 1 and also had other expected bands for s triazine six 6 grams of vacuum stripped product of the formula c 3 n 3 nco 3 obtained by reaction of melamine with oxalyl chloride in o dichlorobenzene is added to 52 grams of isopropanol at room temperature and allowed to stand for 72 hours the resulting hazy solution is filtered and the filtrate stripped under vacuum yielding 8 33 g of a slightly off white solid infrared spectrum shows complete disappearance of nco groups and the appearance of a strong urethane band at 1750 cm 1 an analytical sample is prepared by recrystallization from methanol the structure of the recrystallized solid confirmed by ir nmr and elemental analysis is as follows str6 which can be represented by the formula c 3 n 3 nhcooch ch 3 2 3 10 0 g of the vacuum stripped product obtained from the reaction of melamine with oxalyl chloride in dioxane was short path distilled bulb to bulb at high vacuum to remove a small amount of polymerized dioxane 7 67 grams of a light yellow clear oil was obtained which slowly solidified at room temperature 30 grams of this product was added to 20 ml.
