potatoes as cellulose



potatoes as cellulose defined in 1909 year

potatoes as cellulose - Potatoes as Cellulose;
potatoes as cellulose - Considered as raw material for celluloid, potatoes contain about 20 per cent, of starch and 80 per cent, of water. By the action of nitric acid on starch it is converted into a nitro derivative, and this nitro derivative is practically the same as nitro-cellulose, from which celluloid is made. Hence it is possible to make a celluloid from starch; but after taking into account the price of the potatoes and the cost of evaporating off the 80 per cent, of water, it will be found that paper or cotton is a much cheaper raw material.
