Precautions for Propionyl Chloride

 The following points should be noted when using propionyl chloride in China

 

1. Overview of hazards

Health hazard: its vapor has a strong irritation to respiratory tract and eyes, and causes cough and dyspnea after inhalation. It can also cause skin burns.

 

Flammability hazard: this product is flammable, poisonous and highly irritating.

 

2. First aid measures

Skin contact: Immediately take off contaminated clothing and rinse with plenty of running water for at least 15 minutes. Go to a doctor.

 

Eye contact: Lift the eyelid immediately and rinse thoroughly with plenty of running water or normal saline for at least 15 minutes. Go to a doctor.

 

Inhalation: Quickly leave the scene to fresh air. Maintain airway patency. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. Seek medical advice.

 

Ingestion: Rinse mouth with water and drink milk or egg white. Seek medical advice.

3. Fire control measures

Dangerous characteristics: the vapor of propionyl chloride cas no and air can form an explosive mixture, which is easy to burn  and explode when exposed  to open flames or high heat. It reacts violently with an oxidizer.It will release highly toxic phosgene when decomposed by heat.It reacts with water and water vapor and emits toxic corrosive gas. Its vapor is heavier than air and can diffuse at a lower place to a considerable distance, and will ignite and strile back in case of fire. In case of high heat, the pressure in the container will increase and there is a risk of cracking and explosion.

 

Hazardous combustion products: carbon monoxide, carbon dioxide, hydrogen chloride, phosgene.

 

Fire fighting method: Firemen must wear filtered gas mask (full face masks) or isolated respirators, wear full body fire and gas suit, and put out the fire upwind. Remove the container from the fire as much as possible into an open area. Evacuate immediately if the container in the fire has changed color or produced sound from the safety relief device.

 

Extinguishing agent: dry powder, carbon dioxide, sandy soil. Do not use water or foam to extinguish fire.

What is GLycolic Acid?

  We like to focus on the ingredients of beauty products. But we prefer to touch the product and explore whether it really works. Alpha hydroxy acid is also known as AHA. It includes glycolic acid , lactic acid and citric acid. These products do not meet the needs.   Now we analyze the most popular ingredient in the world - glycolic acid.   Glycolic acid is a naturally occurring substance that is added to skin care products. It is good for the skin and restores skin elasticity and moisturization. The original state of glycolic acid is a powder composed of colorless crystals. It is tasteless. Let's first understand its benefits and its related products.   The Benefits of Glycolic Acid Glycolic acid is very effective for skin treatment because of its high purity. The premise is safe and correct use. Many skin care products contain glycolic acid. Sensitive muscles can also be used. Glycolic acid is non-irritating and it can be used in skin care. Add more glycolic acid to the facial cl

Acetyl Chloride

  Features of Acetyl Chloride Product Name: Acetyl chloride Chemical Formula: C2H3ClO Acetyl chloride cas : 75-36-5 Dangerous Grade: 3.2 Technical Data of Acetyl Chloride ITERMS SPECIFICATION Appearance Colourless transparent liquid Assay ≥99.0% Phosphorus content ≤0.02% Package and Storage: 200kg/drum Store in a cool, dry place. Keep container closed when not in use Application /Application Industries: Acetylation reagent Pharmaceuticals Dye Acetyl chloride is a colorless flammable liquid with a pungent odor. It is violently decomposed by water or ethanol. Dissolved in chloroform, ether, benzene, petroleum ether or glacial acetic acid. Acetyl chloride is an irritant and corrosive agent. Contact with the skin can cause burns, and steam can strongly irritate the eyes and mucous membranes. When people inhale 2 ppm, they can feel the stimulating effect. Short-term exposure to higher concentrations of acetyl chloride may cause death or permanent damage. The amount of aquatic live poisoning

Polyether Polyol Manufacturing ProcessPolyether Polyol Manufacturing Process

  Synthesis of DMC-based polyether polyol by a continuous method   A certain amount of DMC catalyst is taken and uniformly dispersed in a certain amount of small molecule initiator. Add 0.5 kg of the mixture of the initiator in the small test reactor. The vacuum was replaced 1-2 times with N2, and the N2 pressure was maintained at 0.1 MPa. After heating, stirring and raising the temperature to a certain temperature, the quantitative PO was introduced into the continuous autoclave with nitrogen gas for induction. When the induction is successful (the temperature in the kettle rises and the pressure drops), the PO is continuously passed to carry out the reaction. Open the outer loop and continue to pass the PO into the continuous kettle.   When the liquid in the reaction vessel is full, the PO, DMC catalyst and the initiator are continuously added to the kettle at a certain ratio and a certain speed through the power system. Continuous discharge is started when a certain pressure is reac
