- W2364274077 abstract "Through the aldol condensation reaction,α,β-furyl-acrolein were synthesized using furfural and aliphatic aldehydes containing α-H to replace furfural to solve problems of furfural as diluents which was toxic,volatile and irritant in epoxy grouting material of furfural-acetone system.Reaction yield and product properties of n-butyraldehyde,n-valeraldehyde,n-heptylaldehyde and so on with furfural were determined.At the same time,the products of α,β-furyl-acrolein were characterized.Comparing with properties of various α,β-furyl-acrolein as diluents of epoxy grouting material,the 3-furyl-2-ethyl-acrolein(FEA) has the best performance.The results showed the epoxy grouting material of viscosity,28 d compressive strength and tensile shear strength correspond to 80～97.5 mPa·s,92.76～99.98 MPa,5.07～6.06 MPa.Meanwhile,toxicity tests show that the LD50 of FEA was 1260 mg/kg,acute oral toxicity belongs to low poison grade." @default.
