SLM micro reactor / micro autoclave / high pressure reactor

;

 

SLM micro reactor introduction:

SLM micro reactor with high temperature resistance, corrosion resistance, strong production capacity and other advantages, widely used in pharmaceutical, beverage, chemical, paint, resin, research and other industrial sectors. The reaction kettle is a kind of production or experimental equipment which combines the reaction vessel, the reaction condition control system, the raw material feeding and the product export system. Able to complete the preset reaction steps to a higher degree of automation, control of temperature, pressure, mechanical reaction process (mixing, blast, etc.) is an important parameter of reactant / product concentration and strict regulation.

SLM micro reactor main features:

SLM series reactor has the advantages of small volume, simple structure and reliable, economic, durable, complete accessories, include imported miniature DC motor, pressure gauge, explosion-proof device, air inlet valve, a sampling valve, a temperature sensor, can achieve convenient micro reaction test. The kettle body and the heater can be completely separated. Greatly convenient for the reactor demolition work, improve work efficiency.

SLM stirring mode: internal magnetic stirring, seal leakage does not exist and maintenance problems, to ensure that no leakage of rotating parts, more safety test.

SLM mixing motor: Germany imported high power motor, strong and powerful, high speed stability.

SLM into the gas valve: gas inlet needle valve, reliable quality.

SLM sampling valve: easy to react in the process of sampling and analysis of the reaction process

SLM exhaust valve: convenient before reaction on the system of vacuum treatment and replacement of gas, after the reaction as a vent valve.

SLM pressure gauge: real time monitoring of reaction pressure

SLM temperature probe: deep inside the reactor body, real-time monitoring of reaction temperature

SLM heating unit: module heating, heating fast, accurate control.

Structure classification and installation process of

electric heating stainless steel reaction kettle

electric heating stainless steel reaction kettle mainly through the heat carrier furnace transmission of heat conduction oil heating, is a kind of low energy consumption, high temperature and large volume of the ideal equipment. Mainly used in the dairy and sugar and other elements and a variety of drugs to be mixed after the uniform effect. Widely used in chemical, pharmaceutical, food and other industries.

electric heating stainless steel reaction kettle how to classify?

      1, according to the structure can be divided into different forms: open the cover inclined bottom, opening the cover under the conical head, cone head, upper and lower under elliptical head.

;

 

electric heating stainless steel reaction kettle how to install?

      1, autoclave should be placed in the room. When the equipment is equipped with a number of high pressure vessels, it should be placed separately. Each operation room shall be directly to the outside or the outlet of the channel, should ensure that the site with good ventilation equipment.

Stainless steel reaction kettle polishing|Stainless steel reaction kettle polishing

stainless steel reaction kettle inside and outside the surface (in particular, such as electrolytic polishing, mechanical polishing) with a good passivation layer, strong corrosion resistance. Stainless steel reaction kettle inside and outside surface finish is high, the adhesion of the medium is little conducive to corrosion resistance. The less the surface finish of the reaction transfer tube, the less the retention of liquid medium, which is favorable for the washing, especially in the pharmaceutical industry.

stainless steel reaction vessel inner surface electrolytic polishing (electrochemical polishing): electrolytic polishing liquid stainless steel tube inner surface on the anode, polishing liquid in the flow through the low voltage and high current and electrolytic polishing treatment. At this time the inner surface of the tube at the same time to carry out two mutually contradictory process, namely the metal surface passivation layer (containing thick mucous membrane) formation and dissolution. The condition that the film is in passivation is different due to the surface microscopic raised part and the concave part. Because the surface micro convex part and the concave part are in the condition that the film is in a different form, and because the anode is dissolved, the concentration of the metal salt in the anode area is increased continuously, and a high resistance thick mucous membrane is formed on the surface. The film on the convex and concave thickness leads to different surface of the anode current density, discharge dissolving speed, achieve outstanding level of the micro parts in a short period of time, can achieve high degree of finish. Under this kind of action, the inner surface of the tube increases the content and increases the corrosion resistance of the passivation layer on the metal surface.

Reaction material — sodium hydroxide (NaOH) characteristics|Reaction material — sodium hydroxide (NaOH) characteristics

sodium hydroxide (NaOH), commonly known as caustic soda, caustic soda, caustic soda, with another name caustic  soda in Hongkong known as caustic soda, room temperature is a white crystal, with strong corrosion resistance. Soluble in water, its water solution is alkaline, can make phenolphthalein red. Sodium hydroxide is a very common alkali, is one of the essential drugs in the chemical laboratory. Sodium hydroxide in the air easy to absorb water vapor seal to save it must be, and to use the rubber stopper. Its solution can be used as a washing liquid.

shape

molten white particles or strips, are often made of small flakes. Easy to absorb moisture and carbon dioxide in the air. 1g soluble in 0.9ml cold water, 0.3ml boiling water, 7.2ml ethanol, 4.2ml methanol, soluble in glycerol. It is soluble in water, alcohol, or a series of hot. Solution is strongly alkaline. Relative density 2.13. Melting point 318. Boiling point 1390. Half lethal dose (mouse, abdominal) 40mg/kg. Corrosive property. The solution has astringent and greasy feeling.

;   storage

sealed dry preservation.

;  

(that is, can not be placed on the open. The air contains water vapor (H2O), carbon dioxide (CO2), and NaOH water vapor easily deliquescence, easy to react with carbon dioxide to generate sodium carbonate (Na2CO3),  

will deteriorate;

chemical equation for 2NaOH+CO2, Na2CO3+H2O,,  

uses

is widely used in sewage treatment agent, basic analytical reagent, preparation of a standard alkali and a small amount of carbon dioxide and water absorbent, acid and salt making. The manufacture of other containing hydroxyl ions reagent; in the paper, printing and dyeing, wastewater treatment, electroplating, chemical drilling has an important purpose; domestic brands: Tianhui licensing, licensing, licensing gold day.

;  

sodium hydroxide is a good catalyst for many organic reactions. One of the most typical is the hydrolysis of esters:   RCOOR’  +  NaOH  RCOONa  +  R’OH   

security measures  

sodium hydroxide

sealed packaging, stored in a cool dry place. And acid, ammonium type, easy (can) fuel storage and transportation.

;  

do not contact with the skin, if the skin (eyes) contact, rinse with flowing water, apply boric acid solution.

;  

if eaten, water gargle, drink milk or egg white (acid harmless food) and require immediate medical attention.

;   treatment method

abandoned sodium hydroxide can not directly into the sewer, you can use acid neutralization, such as hydrochloric acid, sulfuric acid, etc. (chemical equation for   2NaO>
