Title:
METHOD FOR PRODUCING PURIFIED β-MYRCENE COMPOSITION AND METHOD FOR PRODUCING POLYMER USING SAID β-MYRCENE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2022/249867
Kind Code:
A1
Abstract:
Provided are a purified β-myrcene composition with a reduced polymerization inhibitor content and exhibiting an improved initiator efficiency in anionic polymerization, and a method for producing a polymer using said purified β-myrcene composition. The present invention provides is a method for producing a purified β-myrcene composition comprising: a step of supplying a β-myrcene raw material composition to a distillation equipment; and a step of extracting, by distillation, an amount equal or superior to the total amount of substance groups 1 to 3 calculated from a chromatogram obtained by gas chromatography analysis under the following conditions, of the β-myrcene raw material composition contained in the supplied β-myrcene raw material composition. Conditions for gas chromatography analysis: column used: DB -1 (Agilent Technologies) (stationary phase: dimethylpolysiloxane, inside diameter: 0.32 mm, length: 50.0 m, film thickness: 0.52 μm); temperature rise conditions: 60℃ (12 min hold) → 10℃/min temperature rise → 300℃ (12 min hold), temperature rise time 24 min, total 48 min; injection port temperature: 280℃; injection port pressure: 169.2 kPa; carrier gas: helium; column flow rate: 4.0 mL/min; split ratio: 20; injection quantity: 0.5 μL; injection of beta-myrcene raw material composition as is; injection detector: FID; detection temperature: 300℃; amount of substance group 1: amount calculated, when the relative retention time of the β-myrcene is 1.0, from the peak area ratio of the substance which appears in the range of the relative retention time from 1.29 to 1.78; amount of substance group 2: amount calculated, when the relative retention time of the β-myrcene is 1.0, from the peak area ratio of the substance which appears in the range of the relative retention time from 1.10 to 1.29; amount of substance group 3: amount calculated, when the relative retention time of the β-myrcene is 1.0, from the peak area ratio of the substance which appears in the range of relative retention time from 1.78 to 2.45.
