Aluminum oxide content of secondary butanol aluminum

Yangzhou Zhongtianli, as a professional manufacturer of secondary butanol aluminum, has been continuously recognized by the industry and has won multiple awards and honors over the years. The editor of Tianli would like to share some knowledge about secondary butanol aluminum. Today, we are sharing with you the detection method for the alumina content of secondary butanol aluminum.

How to detect the content of secondary butanol aluminum oxide?

Weigh approximately 10g of the sample to the nearest 0.0001g, place it in a 500mL beaker, add 300ml of water, steam it in a water bath until there is no alcohol odor, add 100ml of water, filter with a quantitative filter paper, and wash with hot water until neutral; The residue is dried in a known weight porcelain crucible and burned to constant weight at 950 ℃± 5 ℃.

Calculate the percentage of aluminum content in secondary butanol aluminum (X) according to formula (1).

G1 2 * MAl

X=------ * ------ * 100% (1)

G2 M

In the equation:

G1- weight after precipitation and burning, in grams (g);

G2- Mass of the sample, in grams (g);

MAl - The numerical value of the molar mass of aluminum, in grams per mole (g/mol) (M=26.982);

M - The numerical value of the molar mass of alumina, in grams per mole (g/mol) (M=101.961).
