Specific installation steps for double-layer glass reactor
After unpacking, check that the main accessories of the unit are complete according to the packing list.
2. Assemble the frame in accordance with the drawings as shown in the figure.
3. Install the electrical box on the top of the right rear pole and tighten the screw. Insert the seven-pin plug. Install the vacuum gauge on the rear end and tighten the screws.
4. According to the height of use, fix the round bracket of the kettle to the vertical pole slider, and place the kettle on the bracket. The semi-circular hoop is used to fix the neck of the kettle, insert the pole slider respectively, and tighten the fixing screws after closing. Attention should be paid to the vertical direction of the reactor body during installation.
5. The stir bar is fixed on the ring clamp of the motor main shaft. The stir bar passes through the middle rotary bearing of the cover, tightens the special connector, and then adjusts the position of the motor, paying attention to the vertical concentricity.
6. The slider on the pole is a stainless steel multi-purpose clamp that adjusts the direction and height in different directions.
7. On the left side of the bottle cap, the 40# standard port plug-in type reflux condenser, the right side 40# is the feeding port connected to the constant pressure funnel, the middle front 24# standard port is inserted into the thermometer casing mouth, and the rear rear hat #34# is Multi-functional spare port, there is no discharge valve at the bottom, the upper and lower sides of the kettle are the circulating fluid inlet and outlet, the lower port is connected to the circulating fluid inlet, and the upper port is connected to the circulating fluid outlet.
8, the installation of glass equipment must be cleaned, the use of Vaseline at each interface to prevent the phenomenon of glass lock, and then apply vacuum grease to prevent air leakage. Press the universal wheel fixing device to stir. If the stirring is stable, the debugging is good.
Epichlorohydrin (ECH)
Epichlorohydrin, 3-Chloro-1, 2 - epoxypropene, chloropropylene oxide ,ECH .
Molecular Formula: CH2OCHCH2Cl, C3H5OCl
Properties: It is a volatile, unstable colorless liquid with irritating odor similar to chloroform and ether. Molecular weight is 92.85, density, 1.1806g/cm3, boiling point, 116.11°C, freezing point, -57.2°C, refractive index (nd20), 1.4382, flash point (open cup), 40.6°C, and ignition point, 415°C. It is slightly soluble in water, miscible with many organic solvents, and able to generate azeotrope with a variety of organic liquids.
Main Applications:
Epichlorohydrin is an important organic industrial chemical and a chlorine-consuming product in fine chemicals, mainly for producing epoxy resin, synthetic glycerin, epichlorohydrin rubber, nitroglycerine explosives, glass fiber reinforced plastics, and electrical insulation products, which are widely used in the chemical industry, light industry, transportation, medicine, electronics and other fields. It also can be used as solvent for cellulose ester, resin, and cellulose ether, and the raw material of plasticizer, stabilizer, surfactant, and chloroprene rubber.
Toxicity and Protection: It is highly toxic, absorbed through the skin, and irritating to skin and mucous membranes. In higher concentrations, it has the function of narcotism. When poisoning occurs, there will be eye irritation, conjunctivitis, rhinitis, lacrimation, cough, fatigue, gastrointestinal disorders, nausea and other symptoms. Serious poisoning may lead to anesthesia or even lung, liver or kidney damages. Lethal concentration of human beings is 20ppm. Lethal dose of rat is 5090mg/kg. The maximum allowable concentration in air is 5ppm (18mg/m3). Production equipment needs to be closed, air, circulating, and the operator, wear protective equipment. In addition, due to intense auto polymerization, epichlorohydrin can not be heated in the fire in case of container burst. As for reaction as reagent, it is appropriate to be diluted with inert solvent and slowly added.
Packaging, Storage and Transport:
As ferric chloride or stannic chloride can promote auto polymerization, epichlorohydrin should be stored in dry, clean iron barrel, 200kg each, and kept in a cool, ventilated, and dry place, away from fire and heat. Store and transport in accordance with the provisions of flammable toxic substances.
