Question

Рассчитайте максимальную массу глицерина,который можно получить при гидролизе свиного сала массой 500г.если его практический выход 96%

Answer 1

500g                            xg
C57O6H110+3H2O=C3O3H8+3C17H35COOH
890g                           92g

x=500·92/890=51.7g
mprakt=51.7·0.96=49.6g

Answer 2

Calculation of Maximum Mass of Glycerin Obtained from Hydrolysis of Pork Fat

To calculate the maximum mass of glycerin that can be obtained from the hydrolysis of pork fat, we need to consider the mass of the pork fat and its practical yield.

Given: - Mass of pork fat: 500g - Practical yield: 96%

To calculate the maximum mass of glycerin, we can use the following formula:

Maximum Mass of Glycerin = Mass of Pork Fat * Practical Yield

Substituting the given values into the formula, we get:

Maximum Mass of Glycerin = 500g * 0.96

Calculating the result:

Maximum Mass of Glycerin = 480g

Therefore, the maximum mass of glycerin that can be obtained from the hydrolysis of 500g of pork fat with a practical yield of 96% is 480g.

Please note that the calculation assumes ideal conditions and a perfect conversion of the pork fat into glycerin. In practice, the actual yield may vary due to various factors such as impurities, side reactions, and incomplete conversion.
