What is Pvp Polyvinylpyrrolidone?

Pvp Polyvinylpyrrolidone is a polymer of vinylpyrrolidone, and also is divided right into soluble PVP and insoluble PVPP (polyvinylpolypyrrolidone) due to different degrees of polymerization. By this method, there is simple to have recurring PVP in the white wine. Recently, making use of soluble PVP has actually ended up being rare. Insoluble PVPP has actually been made use of in the beer sector considering that the very early 1960s. Its loved one molecular mass is more than 700,000. It is a polymer insoluble issue formed by more cross-linking as well as polymerization of PVP.

Pvp Polyvinylpyrrolidone structural formula Polyvinylpyrrolidone PVP is just one of the three major new pharmaceutical excipients. It can be used as a cosolvent for tablets, granules and shots, a glidant for pills, a dispersant for fluid preparations and also colorants, enzymes and also Stabilizers for heat-sensitive drugs, co-precipitants for insoluble drugs, detoxifiers as well as lubes for eye drops, etc. Industrially made use of as foaming polystyrene accessory, gelling agent, stabilizer, fiber therapy agent, paper processing aid, glue and thickener for suspension polymerization. Polyvinylpyrrolidone PVP and also its copolymer CAP are important basic materials for cosmetics and also are mostly utilized in hair care representatives. The film based on the hair is elastic as well as glossy, has superb brushing performance, as well as does not stay with dirt. It makes use of resins of different requirements to meet the Different family member moisture and weather conditions, so it is a vital basic material for styling hair cream, hair spray and also mousse. It can additionally be made use of as a skin treatment moisturizing representative as well as a grease base for cosmetics as a dispersant for hair dyeing, foam stabilizer, and also can improve the uniformity of shampoo. Insoluble PVP is a stabilizer for beer as well as fruit juice, which can boost its openness, color and taste.

Pvp Polyvinylpyrrolidone Uses

  1. Pvp Polyvinylpyrrolidone is made use of for clarifying representative; pigment stabilizer; colloidal stabilizer. It is primarily used for information and also high quality security of beer (the recommendation quantity is 8-20g/ 100L, and also it is filtered and gotten rid of after preserving for 24h), as well as it can also be used in mix with enzymes (protease) and healthy protein adsorbents. It is likewise utilized as a stabilizer for making clear wine and preventing staining (reference dosage is 24-72g/ 100L).
  2. Pvp Polyvinylpyrrolidone is commonly made use of as thickener, emulsifier, lube and also clarifying representative, as well as also as a complex of sterilizing representative PVP-I.
  3. Pvp Polyvinylpyrrolidone is widely used as a disinfectant for medical, aquaculture and livestock. For disinfection of skin and mucous membranes.
  4. As a PolyFilterTM molecule, Pvp Polyvinylpyrrolidone has an amide bond and adsorbs the hydroxyl groups on the polyphenol molecule to form a hydrogen bond. Therefore, it can be used as a stabilizer for beer, fruit wine/wine, beverage wine, prolong its shelf life, and improve its transparency, Color and taste. The product has two specifications: disposable and recyclable. Non reusable products are suitable for little as well as medium-sized business.Renewable products require the purchase of special filtering equipment, but they can be recycled and are suitable for recycling in large breweries.
  5. In daily cosmetics, Pvp Polyvinylpyrrolidone has good dispersibility and film-forming properties of PVP and copolymers. It can be used as a setting agent for styling liquid, hair spray and mousse, sunscreen for hair conditioner, foam stabilizer for shampoo, and wave.Dispersants and also affinity agents in designing and hair dyes. Add PVP to disappearing cream, sun block, as well as depilatory to boost moisturizing as well as lubricating impacts.Taking advantage of PVP’s excellent surface activity, film-forming properties, and no irritation to the skin, no allergic reaction, etc., it has broad prospects for applications in hair care products, skin care products, etc.
  6. Pvp Polyvinylpyrrolidone is used to absorb phenols and tannic acid from aqueous extracts to purify plant enzymes. Used as a chromatographic adsorbent to separate aromatic acids, aldehydes, and phenols.

Preparation of Pvp Polyvinylpyrrolidone

report one,
N-vinylpyrrolidone with a purity of 99.99% was used as the raw material, purified water was used, and sulfur dioxide was used as an initiator, wherein the sulfur dioxide existed in the form of a 10% sulfur dioxide solution.
First, pure water and N-vinylpyrrolidone were added to the polymerization kettle to obtain a solution of N-vinylpyrrolidone with a concentration of 33.3%. Under the condition of 40°C, stirring was carried out. After stirring evenly, 0.54% by weight of sulfur dioxide was added as an initiator. , and then 0.2% by weight of catalyst was added, and the polymerization reaction occurred under these conditions.
The temperature of the polymerization reaction was controlled at 40°C, and the pH value of the solution was adjusted to 9 by dripping concentrated ammonia. After fully stirring, the reaction time was 6.5 hours, and then sampling and analysis were performed to detect the content of N-vinylpyrrolidone. If the content of N-vinylpyrrolidone is less than 20PPm, the reaction is completed. If the content is greater than 20PPm, continue the reaction until the content of N-vinylpyrrolidone is less than 20PPm. The sampling detection adopts high pressure liquid chromatography analysis method.
Under stirring conditions, the Pvp Polyvinylpyrrolidone kettle was cooled to room temperature, and a colorless transparent liquid was obtained in the kettle, and an aqueous solution of Pvp Polyvinylpyrrolidone with a K value of 30 was obtained. The qualified polymer solution is directly introduced into a spray drying system or a drum drying system for drying, the pressure is controlled at -1000pa, and the drying temperature is 160°C, and white Pvp Polyvinylpyrrolidone powder is obtained after drying.
report two,
A preparation method of Pvp Polyvinylpyrrolidone is prepared according to the following steps:
(a) 0.51 mmol of ferrous chloride and 0.2 g of crospovidone were added to the flask, 40 mL of ethanol was added, and stirred uniformly under nitrogen protection;
(b) 160mmol of N-vinylpyrrolidone was added to the flask and stirred uniformly;
(c) adding 0.8mmol methyl 2-bromopropionate to the flask, stirring at 40° C. to carry out a polymerization reaction, reacting for 7 hours, and filtering to obtain a polyvinylpyrrolidone crude material;
(d) 1 g of crospovidone is added to the Pvp Polyvinylpyrrolidone crude material and mixed, after stirring, filtering, and after the solvent is distilled off under reduced pressure, then washed with anhydrous ether to obtain polyvinylpyrrolidone;
Wherein, the adopted crospovidone has a particle size of 5 μm and a bulk density of 0.4 g/mL.
report three.
A kind of preparation method of high molecular weight Pvp Polyvinylpyrrolidone, its steps are as follows:
First, add 750kg of pure water into the polymerization kettle, adjust the pH value to make the pH value > 7.0; add 250kg of NVP to the pure water under stirring, heat up to about 50-55°C under the protection of nitrogen, remove it with ultrasonic waves Oxygen for 30 minutes; when the polymerization kettle temperature reached 70 ° C, 2.5kg of azobisisobutylimidazoline hydrochloride was added to the reaction kettle, and a polymerization reaction occurred under this condition; after 6 hours of constant temperature of reaction, start sampling Analyze and detect the NVP content in the sample. When the NVP content is less than 0.002%, lower the temperature of the reaction system to below 40 degrees, and end the reaction to obtain a polymer solution with a K value of about 55; this polymer solution is dried by spray drying. , a white powdery product was obtained.
