| Abstract: | Based on the Wittig reaction principle,fluorescent whiter DX.EB was synthesized from 2-nitril-benzyl-dimethyl-phosphatidate(1),4-nitril-benzyl-dimethyl-phosphatidate(2),terephthalalic aldehyde and methyl sodium.The synthetic technology of DX.EB was studied.The synthetic technology of DX.EB was studied.The yield was 74.72% at n(1): n(2) = 1: 1.5,dropped methyl sodium at 40℃. |
