Benzinic anhydride is a special chemical in its solid form at room temperature and in liquid form at temperatures greater than 130 ℃. A large amount of steam is produced in the production of phthalic anhydride, which is often used for the use of benzonic anhydrates with heat, but many of the benzonic anhydrates are now used for the most part by the thermal hydrophobic valve. Thermostatic hydrophobic valve can make use of condensate to develop heat effectively, which can not meet the heat requirement for liquid phthalic anhydride with temperature greater than 130 ℃. Benzonic anhydrates with heat is recommended to adopt mechanical hydrophobic valve.
