Aluminum octenylsuccinate starch is a new type of modified starch with many unique properties and uses. This article will introduce in detail the preparation method, properties, applications and market prospects of octenylsuccinic aluminum starch.
First, the preparation method.
The preparation method of aluminum starch octenylsuccinate mainly includes the following steps:
1.Raw material preparation: Choose high-quality starch as raw materials, such as corn starch, tapioca starch, etc.
2.Pretreatment: The starch is pre-treated, such as washing, drying, crushing, etc., for subsequent reactions.
3.Octenylation: The octenylation group is introduced on the starch molecule to make the starch more reactive.
4.Succinylation reaction: The introduction of succinic acid groups on octenyl starch gives the starch better thermal stability and anti-aging properties.
5.Aluminization reaction: Aluminum ions are introduced on the starch after succinylation to make the starch have better acid and alkali resistance.
6.Drying and crushing: The starch after the reaction is dried and pulverized to obtain an aluminum octenylsuccinate starch product.
2. Nature. Aluminum starch octenylsuccinate has the following properties:
1.High reactivity: Due to the introduction of octenyl and succinic acid groups, starch has higher reactivity and can be cross-linked with other substances.
2.Good thermal stability and anti-aging: Due to the introduction of succinic acid group, starch has better thermal stability and aging resistance, and can maintain good performance in high temperature and strong acid and alkali environment.
3.Acid resistance and alkali resistance: Due to the introduction of aluminum ions, starch has better acid and alkali resistance, and can maintain good performance in different pH environments.
4.Good film-forming: Because octenylsuccinate aluminum starch has good film-forming, it can be used to make packaging films, waterproof films, etc.
5.Biodegradability: Because octenylsuccinate aluminum starch contains biodegradable groups, it has good biodegradability and is environmentally friendly.
3. Application. Aluminum starch octenylsuccinate has a wide range of applications, mainly including the following aspects:
1.Food processing: Because octenylsuccinate aluminum starch has good film-forming, acid resistance and alkali resistance, it can be used to make food packaging films, waterproof films, etc. At the same time, it can also be used as a thickener, stabilizer, etc. in food processing.
2.Pharmaceutical field: Aluminum starch octenylsuccinate has good biocompatibility and biodegradability, and can be used to make drug carriers, tissue engineering materials, etc.
3.Paper industry: Aluminum starch octenylsuccinate can be used as a paper coating agent and reinforcing agent in the papermaking process to improve the strength, waterproofness and other properties of the paper.
4.Construction industry: Octenylsuccinate aluminum starch can be used to make building waterproof coatings, sealants, etc., to improve the waterproof performance and durability of buildings.
5.Other fields: In addition to the above application fields, octenylsuccinate aluminum starch can also be used in textile, leather, cosmetics and other fields.
Fourth, market prospectsWith people's requirements for environmental protection, health, safety, etc., the demand for new modified starch is also increasing. As a new type of modified starch, aluminum octenylsuccinate starch has a wide range of application prospects and market potential. In the future, with the continuous progress of technology and the continuous growth of market demand, the application field of octenylsuccinate aluminum starch will be more extensive, and the market prospect will be broader.
