DOCUMENT TYPE: Patent CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) OH group-contg. cyclic ethers are prepd. by reaction of R1CR2:CH(CH2)nCHR3OH (R1-R3 = H, C1-10 alkyl, aryl; n = 1-7) with peroxides in solvents in the presence of titanosilicate catalysts. 3-Buten-1-ol was cyclized in 2-BuOH in the presence of TS-1-type titanosilicate and H2O2/H2O at 25° for 18 h to give 82% 3-hydroxy-tetrahydrofuran.

DOCUMENT TYPE: Journal CA Section: 45 (Industrial Organic Chemicals, Leather, Fats, and Waxes) Section cross-reference(s): 67 Catalytic dehydration of 1,4-butanediol was investigated over ZrO2 with monoclinic crystal phase at temps. of 275-425°. In the reaction, 3-buten-1-ol was effectively produced together with THF over ZrO2 at 300-375°. 3-Buten-1-ol and THF were produced competitively, and the yield of 3-buten-1-ol increased with increasing the contact time. Formation of byproducts, such as 2-buten-1-ol, 2-butenal, and 1-butanol, was suppressed over ZrO2 at 325°.
