Description

A kind of cleaning agent prepared by utilizing the tail water of producing propyl gallate and preparation method thereof

technical field

The application relates to the technical field of daily chemical production, in particular to a cleaning agent prepared by using the tail water of propyl gallate production and a preparation method thereof.

Background technique

Kitchen oil is a common dirt in daily life. The formation of heavy oil stains in the kitchen is caused by the adsorption of the oil fume vaporized at high temperature to the surface of the range hood or the wall during the cooking process. and rust or shedding caused by rust, aging, etc. during use. These scales are usually composed of at least one or two or more kinds of scales, which are then oxidized by air and microbially fermented to form complex scales.

The removal of heavy oil and dirt in the kitchen is mainly achieved by using surfactants, alkalis and solvents. At present, the classification of kitchen cleaning products on the market can be divided into strong type, ordinary type and mild type. Among them, the strong product has a high content of oily water decomposer, a large content of oily softener, strong detergency, and is suitable for heavy scale removal; ordinary products have less alkali content and less solvent content, and are suitable for multi-surface use; mild products The alkaline content is very low, and it mainly relies on surfactants for decontamination, which is suitable for daily maintenance. However, strong products usually add a large amount of oily water hydrolysis agent, which is highly irritating and corrosive, making it difficult to meet the needs of consumers; while common and mild products use natural glucoside surfactants, although mild and safe The performance is high, but the oil removal performance is questionable. Moreover, the existing strong, common and mild kitchen heavy oil cleaning products on the market cannot clean the rust and protect the damaged metal during use.

Propyl gallate can be prepared by acid-alcohol esterification of gallic acid, a hydrolyzed product of tannic acid, and n-propanol, or tannic acid can be used as raw material to directly produce propyl gallate by transesterification. But no matter which method, the tail water of producing propyl gallate needs to be treated, and the propyl gallate contained in the tail water is wasted.
