Definitions

• the product is isolated from the suspension by dosing, the plant is washed away from the water for drying and drying.
• the output of phthalimide is 90-96 $ from the theory, the melting point is 232-235 ° C (patent USL L 3819648, CL 260-326, published 1975).
• the capacitive appliance with a stirrer, a disassembler, a socket and a built-in serpentine loads the carbamide, disables its agitator, loads an unloading, and unloads
• the high ratio between phthalic anhydride and carbamide is 1: 0.8; the coefficient of loading the reaction is 0.15.
• the appliance and the coil of the appliance are fed with the process coupler with the transmitter - 2 - ⁇ ⁇ 80 ° ⁇ . Upon reaching a reactionary mixture of ⁇ 30- ⁇ 35 ° C, carbamide is decomposed, and reactivation of the reaction begins.
• the resulting macebide is water-borne, it is cooked for 2–30 minutes and turns on the stirrer. If the m ⁇ -shuffle is not pumped, the mass of the manual b ⁇ for the hatch is six. The mixed mass is stirred for 30-60 minutes, the resulting suspension of the centrifuge is removed, the plant is washed with water and discharged.
• the temperature of the product is $ 91-92, the melting point is 232-237 ° ⁇ , the moisture content is $ 4-6.
• Raw materials of raw materials make up the total anhydride II 00 kg / t, and for the carbamide - 375 kg / t.
• Waste water for the supply of suction and washing the precipitate is 9000 kg / t, a large amount of water - 9250 kg / t, because there is a lot of waste gas - 150
• the object of the present invention is the compilation of the phthalimide device, which is respected by the user.

• the volume of the puffed mass is, therefore, instantly increased up to ⁇ 50- ⁇ 60 ° ⁇ , and then it decreases by 5- ⁇ raum ⁇ .
• the inactive mass in this unit provides a dry, small-sized phthadimide with the exclusion of separate large-sized external salts. You save up to ⁇ 50- ⁇ 70 ° C, keep it at the indicated temperature a minute before you take out the ammunition, it takes out the load. - 5 -
• the mixer is equipped with electronic accessories, a unit for cooling and cooling, and a cavity that has a connection for loading 20 generations, a partition is available. After the charge is turned on, the mixture is pressurized, the mixer is set to a pressure of 0.090-0.098 ⁇ Pa and the mixture is heated, the mixture is heated to a temperature of 0 ° C. The resulting heaters give a heat of 25 ° C to 55 ° C and maintain a specified heat of 60 minutes. At the end of the batch, the obtained product and stirring waits for the room temperature.
• Example 3 in a mixture, heated to a mixture of 6 ⁇ -90 ° ⁇ , load 444.36 g (3 mol) of anhydrous acid and 126.1 g of carbamide (2, 1 med); ), pressurizes the mixer, creates a residual pressure of 0 0, 090-0, 098 réelle Pa and stirs it. At 95–5 ° C, the mixture is melted, the resulting melt is heated to 70 ° 0 and is kept at this temperature for 10–15 minutes. At the end of the batch, the waste mass is cooled and mixed until the room temperature is very high.
