Objective:Improving the earning ratio on sodium salt azeotropism crystallization in the process of refining Penicillin is vital important to the total rates of return in producing Penicillin.───前言: 目的:提高青霉素提炼过程中钠盐共沸结晶的收率,对于青霉素生产过程的总收率的提高非常重要。
Improving the rate of return on sodium salt azeotropism crystallization by means of improving equipment───改进设备提高青霉素钠盐共沸结晶收率
The high quality of the product with recovery of 82% was obtained by cancelling azeotropism of dimethyl carbonate and methanol.
Results:the es- say illustrates that it improves the quality of Penicillin and the rate of return on azeotropism crystallization.
Objective:Improving the earning ratio on sodium salt azeotropism crystallization in the process of refining Penicillin is vital important to the total rates of return in producing Penicillin.
Used as a component of solvents in the process of the azeotropism, and could partly replace toluene, xylene and methyl isobutyl ketone (MIBK).
