主要用途:

間戊二烯主要用于生產石油樹脂、共聚彈性體,以及固化劑、農藥、香料等。

包裝形式:

散裝

儲存方式:

低溫儲藏、避免陽光直射、遠離熱源、禁止明火、保持良好通風。應與氧化劑、鹵素(氟、氯、溴)、酸類等分開存放。庫內照明、通風設施應采用防爆型,開關設在庫外。

運輸方式:

按I級危險品運輸方式運輸。用槽車運輸。

安全注意事項:

1. 間戊二烯易燃、易爆、在大氣中的爆炸極限為2.6~10.3% (v/v) ,蒸汽閃點-28℃,儲存物品的火災危險性分類屬甲級易燃物品(GBJ16《建筑設計防火規范》),危險性類別屬第3.1類(GB6944)。因此一切預防措施應考慮如何避免形成爆炸氣氛,并避免與硝酸、硫酸、氯磺酸等氧化劑接觸。 2. 當間戊二烯發生初期火災時,可用泡沫、干粉、二氧化碳滅火器滅火,也可用砂土等滅火,不可用水作滅火劑。 3. 間戊二烯沸點較低,應儲存于陰涼干燥處。夏天在室外堆放時,要采取淋水等降溫措施,并避免中午高溫時運輸。 4. 間戊二烯產品運輸中,運輸車輛必須設立危險品標記,采取必要的安全措施。 5. 間戊二烯蒸汽有低毒,當吸入一定量的蒸汽后,身體將產生不適。因此要保持工作場所良好的通風狀態,并配備沖洗龍頭。如出現明顯不適時,應即離開現場,呼吸新鮮空氣,呼吸困難時,給輸氧。呼吸停止時,立即進行人工呼吸。如較長時間出現不適或嚴重不適時,應去醫療機構就醫。
