The boiling point is 34°C, right? Isoprene is a colorless, volatile liquid. Insoluble in water, specific gravity 0.68, flash point ≤-54 °C, autoignition temperature 220 °C, explosion limit 1.1–10 % (φ). Its vapor can form explosive mixtures with air, and it is highly prone to combustion and explosion when exposed to open flames or high temperatures. In the event of high temperatures, a polymerization reaction can occur, releasing large amounts of heat that may cause the container to rupture and lead to an explosion. Its vapor is heavier than air, allowing it to spread over considerable distances at lower levels; it will catch fire and reignite when exposed to a source of flame. Inhaling air containing high levels of isoprene has a **stimulating effect on the human nervous system. Typically, products are treated with inhibitors to prevent polymerization. Store in a cool, well-ventilated warehouse. Keep away from flames and heat sources. Operate in a closed environment with thorough ventilation; smoking is strictly prohibited in the workplace. To prevent the formation of peroxides, the equipment should be purged with nitrogen before isoprene is introduced, ensuring that its oxygen content is ≤0.05 %. High-purity nitrogen is used for pressure holding.
What is used to store and transport products in large-scale production?
The poster can check the saturated vapor pressure of isoprene; it is recommended to choose a storage method appropriate for liquefied hydrocarbons. Such as storage at normal temperature and pressure (full-pressure type) or at low temperature and normal pressure (full-freezing type). As for transportation, it seems that all methods work, whether by rail, road, water, or pipelines. The question posed by the original poster is quite broad, which makes it difficult to answer. The poster can refer to the storage method for C5 components, or simply opt for storing it alongside liquefied hydrocarbons.
