The sodium L-glutamate is reported as an efficient catalyst for the cross-linking between 1,2,3,4-butanetetracarboxylic acid (BTCA) and cellulose. Results presented ester absorbance of the treated fabrics strongly increased in the presence of the homemade L-glutamate salt, a mixture of L-glutamic acid (LGA) and NaOH at a specific ratio. Importantly, anti-wrinkle properties of the treated fabrics were significantly improved. Based on the relative concentration calculation, L-glutamate promoted the reaction of BTCA with cellulose by accelerating the formation of BTCA anhydrides and the esterification of anhydrides with cellulose. Besides, the improved anti-wrinkle property was partially attributed to the fact that the generated LGA reacted with cellulose and formed ionic cross-linking networks through amino groups with carboxyl groups in BTCA, which was confirmed by the Fourier transform infrared spectra and the computational calculations. Through detailed comparisons, L-glutamate catalyzed fabrics showed as good durability as sodium hypophosphite, indicating a possible alternative for phosphorus-containing catalysts.

据报道，L-谷氨酸钠是1,2,3,4-丁烷四羧酸（BTCA）和纤维素之间交联的有效催化剂。结果表明，在自制的L-谷氨酸盐，L-谷氨酸（LGA）和NaOH以特定比例的混合物的存在下，处理过的织物的酯吸收率大大提高。重要的是，处理过的织物的抗皱性能得到了显着改善。根据相对浓度计算，L-谷氨酸通过促进BTCA酸酐的形成和酸酐与纤维素的酯化反应，促进了BTCA与纤维素的反应。此外，改善的抗皱性能部分归因于这样的事实，即生成的LGA与纤维素反应，并通过BTCA中的带有羧基的氨基形成了离子交联网络，傅立叶变换红外光谱和计算结果证实了这一点。通过详细的比较，L-谷氨酸催化的织物显示出与次磷酸钠一样好的耐久性，表明它可能是含磷催化剂的替代方案。
