Paragraph 0131; 0132, (2021/07/02)
The invention relates to a composition excellent in stability during storage and stability during utilization, and relates to a method of producing the composition. The composition includes a compound (A) represented by general formula (1) and a compound (B) represented by general formula (2), and includes 0.00002 to 0.2 parts by mass of the compound (B) with respect to 100 parts by mass of the compound (A), [in-line-formulae](R1—COO)n—R2—(NCO)m??(1)[/in-line-formulae] [in-line-formulae](R1—COO)n—R2—(R3—R1)m??(2)[/in-line-formulae] wherein in general formulae (1) and (2), R1 is an ethylenically unsaturated group having 2 to 7 carbon atoms; R2 is a (m+n)-valent hydrocarbon group having 1 to 7 carbon atoms and optionally contains an ether group; R1 and R2 in the general formula (1) are the same as R1 and R2 in the general formula (2); in general formula (2), R3 is —NHC(═O)—; and n and m each represent an integer of one or two.
ISOCYANATE PRODUCTION METHOD

Paragraph 0447-0450; 0459; 0478, (2020/05/02)
An isocyanate production method according to the present invention is a method in which an isocyanate is produced by subjecting a carbamate to thermal decomposition, and includes: a step of preparing a mixture liquid containing the carbamate, an inactive solvent and a polyisocyanate compound; a step of conducting a thermal decomposition reaction of the carbamate by continuously introducing the mixture liquid into a thermal decomposition reactor; a step of collecting a low-boiling decomposition product by continuously extracting the low-boiling decomposition product in a gaseous state from the reactor, the low-boiling decomposition product having a boiling point lower than the polyisocyanate compound; and a step of collecting a high-boiling component by continuously extracting, from the reactor, a liquid phase component which is not collected in a gaseous state at the step of collecting the low-boiling decomposition product.
