INTRODUCTION

5-Methyl-3-vinyl-2-oxazolidinone (V-MOX) is a highly reactive monomer valued for its low viscosity, mild odor, and excellent reactivity. It is widely used as a reactive diluent in UV-curable inks and coatings, where it enhances adhesion, produces brighter colors, and improves safety compared to conventional diluents. In addition, V-MOX serves as a key building block in the synthesis of kinetic hydrate inhibitor (KHI) polymers, which are applied in oil and gas production to prevent hydrate blockages in pipelines.

Manufacture

V-MOX can be synthesized via a two-step process. In the first step, Cu(II)-catalyzed cyclization of (±)-1-amino-2-propanol with carbon monoxide under an oxygen atmosphere affords 5-methyl-2-oxazolidinone. This intermediate then undergoes ruthenium-catalyzed vinylation with acetylene to give V-MOX in good yields. Alternatively, V-MOX can also be obtained through pyrolysis of 3-(1-hydroxyethyl)-5-methyloxazolidin-2-one.

Structure

Applications

V-MOX is a versatile chemical intermediate and functional monomer, primarily used in specialty polymers and coating. The main areas of application include:

Printing Inks & 3D Printing:
V-MOX acts as a reactive diluent in UV-curable inks and coatings, where it enhances adhesion to difficult substrates (plastics, metals, glass), and Improves gloss, scratch resistance, and weatherability.
UV Curing:
As a reactive diluent, VMOX reduces the viscosity of formulations and participates in the UV curing process itself, leading to polymers with good adhesion, durability, and vivid colors. 
Oil & Gas Industry:
Serves as a building block for kinetic hydrate inhibitor (KHI) polymers, preventing gas hydrate blockages in subsea pipelines. Offers improved stability and efficiency in flow assurance applications.
Materials Science:
It serves as a building block for creating new polymers and materials with specific mechanical and chemical properties, including potential use in biomedical applications.
Coatings & Surface Modification:
Imparts durability and chemical resistance when incorporated into coating formulations. Supports development of thin, uniform, and crosslinked films.
Adhesives & Sealants:
Contributes to strong bonding and fast curing under UV or electron-beam radiation. Especially valuable in electronics assembly and packaging.
