1 Source of materials
The mixture of syringic acid (121 mg, 0.6 mmol) and of α-methylbenzylamine (80 ml, 0.6 mmol) were dissolved in a mixture of 3.5 ml acetonitrile and 1.5 ml ethanol, and the resulting mixture was stirred at 60 °C for 2 h to obtain a clarified solution. Cool to 40 °C, and then put it in a 10 ml glass bottle. The glass bottle was covered with a porous film. Single crystals of the title compound were obtained after 1 day.
2 Experimental details
Absorption corrections were applied by using multi-scan program. 1 Using Olex2, 2 the structure was solved with the ShelXT 3 structure solution program and refined with the ShelXL 4 refinement package. The H atoms were fixed, fixed Uiso were set to 1.2 times of all C(H) groups, C(H, H) groups and N(H, H) groups; 1.5 times of C(H, H, H), groups, O(H) groups and O(H, H) groups.
3 Comment
Syringic acid (SA) has interesting applications on pharmaceutical, fragrance and favour industries. It is the low molecular weight compound obtained through an oxidation process of the lignin. 5 Separation and purification processes to obtain purified SA from oxidation products of lignin are important. 6 Accordingly, the development of sustainable purification and recovery processes of high-value compounds from industry waste, suitable for industrial implementation, is nowadays a crucial need. In this work, a salt of SA with a phenylethylamine (PEA) is designed, synthesized, and characterized. It can provide a method for purifying SA. The title structure was refined to contain one host SA anion and one guest PEA cation: the nitrogen atom of the guest is protonated, while the C–O bond lengths of the host carboxylic group have lengthened from the usual values of 1.20 Å as occurs in the C=O double bond to 1.254(3) Å in the delocalized COO– anion. This is in accordance with the publication of Park 7 which discusses the salt-cocrystal continuum as a function of pKa of acid–base structures: the pKa of SA is 4.34 while that of protonated PEA is 9.73 resulting in a pKa of 5.39. This is a sufffciently large difference to predict the formation of a salt. Bond lengths are as expected. 8 , 9
