Biomass-based 1,4-butanediol (BD) was produced with high selectivity from diacetoxybutane (DAB) and alcohol using a KHSO₄ catalyst, which could be recycled. The DAB used in this reaction could be produced from furan, which, in turn, can be easily produced from furfural. The conversion of furfural to BD was carried out under mild conditions such as low H₂ pressure (0.69 MPa). These processes produce not only tetrahydrofuran (THF) but also alkyl esters, which are industrial important chemicals. Alkyl esters are alternatives to benzene, toluene and xylene (BTX) solvents. It was confirmed that the BD synthesized in this paper was entirely biobased because its biobased carbon content was 99.63%, as determined by accelerator mass spectrometry based on ASTM D6866.

使用KHSO ₄催化剂，可以由二乙酰氧基丁烷（DAB）和醇以高选择性生产基于生物质的1,4-丁二醇（BD）。该反应中使用的DAB可以由呋喃生产，而呋喃又可以容易地由糠醛生产。糠醛向BD的转化在温和的条件下进行，例如低H ₂压力（0.69 MPa）。这些方法不仅产生四氢呋喃（THF），而且产生烷基酯，它们是工业上重要的化学物质。烷基酯是苯，甲苯和二甲苯（BTX）溶剂的替代品。证实了本文合成的BD完全是生物基的，因为它的生物基碳含量为99.63％，这是通过基于ASTM D6866的加速器质谱法测定的。
