Why morpholine dosing better than ammonia dosing in boiler feed water?
Morpholine is often preferred over ammonia for dosing in boiler feed water because it has lower volatility, lower potential for corrosion, and it offers better pH stability. Additionally, morpholine provides effective protection against both acidic and alkaline corrosion in the boiler system, making it a more versatile and reliable option compared to ammonia dosing.
What is polyvinylidenechloride?
Polyvinylidene chloride (PVDC) is a type of polymer that is commonly used as a barrier coating in food packaging to prevent moisture and oxygen transmission. It is known for its high barrier properties, transparency, and heat resistance. PVDC is often used in conjunction with other materials to create multi-layer packaging films.
What is the name of a reaction between an acid and an alkali?
The reaction between an acid and an alkali is known as a neutralization reaction. In this reaction, the acid reacts with the alkali to form water and a salt.
What type of reaction is between magnesium and oxygen?
The reaction between magnesium and oxygen is a combustion reaction, also known as a redox reaction. Magnesium reacts with oxygen to form magnesium oxide.
What is the reaction between hydrogen peroxide and acetic acid?
The reaction between hydrogen peroxide and acetic acid produces water and oxygen gas as products. This reaction is known as a decomposition reaction.
What will get in the reaction between PVC and morpholine?
The reaction between PVC (polyvinyl chloride) and morpholine is likely to result in the formation of PVC-morpholine adducts. These adducts can improve the flexibility, thermal stability, and resistance to heat aging of PVC. The reaction is often used in the modification of PVC to enhance its properties.
How morpholine is used for PVC identification?
Morpholine can be used in the identification of polyvinyl chloride (PVC) through a chemical reaction that leads to the formation of specific derivatives. When morpholine is applied to PVC, it can cause the release of hydrochloric acid (HCl), which is a characteristic reaction of PVC. By analyzing the resulting products or observing changes in properties, such as solubility or color, morpholine aids in confirming the presence of PVC in a sample. This method is particularly useful in forensic and material analysis contexts.
How do you differentiate between PVC and pvdc?
PVC (polyvinyl chloride) is a thermoplastic polymer commonly used in pipes, vinyl flooring, and credit cards. PVDC (polyvinylidene chloride) is a barrier material used in packaging to prevent moisture and gases from penetrating. PVC is rigid and can be clear or colored, while PVDC is flexible and typically used as a coating on packaging films.
What is the difference between PVC and pvdc?
The difference is that PVC is Polyvinyl Chloride and PVDC is Polyvinylidene Chloride. PVDC is a stronger material for things like blister packaging, while PVC works better in construction applications. However, many companies will use both together for a more reinforced product solution.
What is the chemical formula of morpholine?
C4H9NO

Why should PVDC film be used insted of PVC film in pharma packaging?
as pvdc has better barrier-properties for moisture and oxygen, hence protecting packed pharmaceuticals from aging, increasing stability and shelf-life. The PVDC is generally coated on the PVC-base film. regards Luc
Why is polyvinylidene chloride a stickier plastic than polyethylene'?
Polyvinylidene chloride (PVDC) is stickier than polyethylene due to its chemical structure and properties. PVDC has a higher polarity and stronger intermolecular forces, which enhance its adhesive qualities. Additionally, PVDC's ability to form hydrogen bonds contributes to its stickiness, making it more effective in applications requiring adhesion compared to the relatively non-polar and less adhesive polyethylene.
What is polyvinylidenechloride?
Polyvinylidene chloride (PVDC) is a type of polymer that is commonly used as a barrier coating in food packaging to prevent moisture and oxygen transmission. It is known for its high barrier properties, transparency, and heat resistance. PVDC is often used in conjunction with other materials to create multi-layer packaging films.
What is the difference between neutralization salt?
Salts are the products of a reaction between an acid and a base; this reaction is called neutralization reaction.
What is the difference between neutralization and salts?
Salts are the products of a reaction between an acid and a base; this reaction is called neutralization reaction.
Why is plastic wrap made of polyvinylidene chloride stickier than plastic wrap made of polyethylene?
Plastic wrap made of polyvinylidene chloride (PVDC) is stickier than that made of polyethylene due to its chemical structure, which allows for stronger intermolecular forces. PVDC has polar bonds that enhance adhesion when wrapped around surfaces, creating a tighter seal. In contrast, polyethylene is a non-polar polymer with weaker van der Waals forces, resulting in less stickiness and a less effective seal. This difference in molecular properties makes PVDC more suitable for applications requiring a secure cling.
