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.

Difference Between Sulfate And Sulfonate In Shampoo

  Sulfates and sulfonates have two things in common. First, they're all anionic surfactants. Second, they are often used for personal care applications. But there are many differences. They have different molecular mechanisms. They have different functions and they have different raw materials.   Sulfates Sulfate is a compound. It has carbon bonds and oxygen and sulfur bonds. They include substances such as sodium lauryl sulfate and sodium lauryl ether sulfate.   At low pH, these substances plus the c-o-s bond hydrolyze to produce alcohol and inorganic sulfate. At a high pH, sulfate is stable in the base and, if ethoxylated to a relatively high level, produces a low-foaming alkali-soluble surfactant. Sulphates can be prepared by reaction of fatty alcohol or fatty alcohol ethoxylates with reagents such as SO3 or chlorosulfonic acid (CSA).   The reason shampoo becomes thick foam in the shower is that it contains sulfate. Most shampoos and household cleansers contain su...

Two Different Types of Anionic Surfactants

  Anionic surfactant is a kind of product with the longest history, the largest output and the most varieties among surfactants. According to the structure of hydrophilic groups, anionic surfactants can be divided into sulfonates and sulfates, which are the main categories of anionic surfactants.    The  anionic surfactants definition  is a must-known concept for many people working in the chemical industry. The various functions of surfactants are mainly manifested in changing the properties of the liquid surface, liquid-liquid interface and liquid-solid interface, of which the surface (interface) of the liquid is the most important.   Sulfate-type anionic surfactants mainly include fatty alcohol sulfate (also known as primary alkyl sulfate) and secondary alkyl sulfate ： 1.  Fatty alcohol sulfate (ester) salt (FAS or AS). The general formula of fatty alcohol sulfate is: ROS0-3M+, R is alkyl, M+ is sodium, potassium, ammonium, ethanolamine and other ca...

Polyether 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 pr...
