Effect of the variation of reaction parameters on the activity of the 1%Pd-CS/MMT catalyst in the 2-hexyn-1ol hydrogenation: catalyst dosage (a); 2-hexyn-1-ol amount (b); concentration of hydrogen in hydrogen–helium mixture (c); temperature (d). Reaction conditions: 40 °C, 0.1 MPa, 100% H₂, catalyst—25–100 mg, 2-hexyn-1-ol—0.25 mL, ethanol—25 mL (a); 40 °C, 0.1 MPa, 100% H₂, catalyst—50 mg, 2-hexyn-1ol—0.10–1.00 mL, ethanol—25 mL (b); hydrogen percentage in H₂:He gas mixture—30–100 vol%, catalyst—50 mg, 2-hexyn-1ol—0.25 mL, ethanol—25 mL (c); 25–40 °C, 0.1 MPa, 100% H₂, catalyst—50 mg, 2-hexyn-1ol—0.25 mL, ethanol—25 mL (d).
