Uses
2-Vinylnaphthalene is employed in the synthesis of various copolymers such as Poly (sodium styrenesulfonate-co-2-vinyl-napthalene) copolymer and Poly (2-vinylnapthalene-alt-maleic acid)-graft-polystyrene. The latter finds applications as a photoactive polymer micelle and stabilizer for polystyrene latexes.
Application
Used in plastic scintillators, neutron detectors and other demanding device applications. Poly(2-vinyl naphthalene) is synthesized by free radical or anionic living polymerization 2-vinylnaphthalene.
Definition
ChEBI: 2-vinylnaphthalene is a vinylnaphthalene carrying a vinyl group at position 2.
General Description
2-Vinylnaphthalene (2VNP) can be prepared by the alkylation of naphthalene to I-and 2 ethylnapthalenes followed by dehydrogenation, or by oxidation followed by dehydration. 2VNP is the monomer for poly-(2-vinylnapthalene).
Purification Methods
The flammable solid can be fractionally distilled under reduced pressure using a spinning-band column; dry it with CaH2 and again distil it under vacuum. It crystallises from aqueous MeOH, EtOH (m 66o) or pet ether (m 66-66.5o). Store it in sealed ampoules in a freezer. The picrate has m 91-92o (from EtOH). [Beilstein 5 III 1775, 5 IV 1833.] It is an irritant.
