Allyl Benzyl Ether

Description

Base polymer primarily from isobutylene with some 1- and 2-butene.

Chemical properties

Colorless liquid. B.P. 205℃. Sweet-ethereal odor with somewhat fruity undertone. Could find use in perfumery, but the matetial as such is not very interesting or characteristic, does not offer any specific olfactory advantage.

Chemical properties

Colorless to Almost colorless clear liquid.

Characteristics

Low odor, good heat stability, low color and broad compatibility with elastomers, plastics and tackifying resins.
Does not readily oxidize. Contains no cyclic compounds.

What are the applications of Application

Base polymer in hot melt adhesives and paper-laminating, extender and viscosity modifier in caulks and sealants and waterproofing agent in wire and cable applications.
Cosmetic additive, metal working lubricant, polymer lubricant and modifier for tire sealants.

Preparation

Benzyl alcohol (108 mg, 1 mmol) was converted to allyl benzyl ether 11 in 96% yield in 4×5 h. IR (neat): 1630, 1090 cm–1 ; 1H NMR: d 7×34 (m, 5H), d 5×9–6×0 (m, 1H), d 5×17–5×35 (m, 2H), d 4×5 (s, 2H), d 4×04 (d, J = 1×46 Hz, 2H).
