Uses

Used in Agricultural Applications:
2-(2,4-Dichlorophenoxy)propyl acetate is used as a systemic herbicide for the control of broadleaf weeds in various crops. It is applied to target weeds that compete with crops for resources, thereby enhancing crop yield and quality.
Used in Non-Crop Areas:
In non-crop areas, 2,4-DP ester is used as a weed control agent to manage unwanted vegetation that may interfere with landscaping, infrastructure, or recreational areas. Its quick absorption and translocation properties make it an effective solution for maintaining clear spaces.
Used in Environmental Management:
2-(2,4-Dichlorophenoxy)propyl acetate is utilized in environmental management practices to control invasive plant species that can disrupt ecosystems and biodiversity. Its targeted application helps in preserving natural habitats and maintaining ecological balance.

A method for preparing 2, 4 - dichlorophenoxyacetic acid (by machine translation)

The invention provides a 2, 4 - dichlorophenoxyacetic acid preparation method, comprises the following steps: A) halogenated acetate with 2, 4 - dichlorophen salt reaction, to obtain 2, 4 - dichlorophenoxy ester; B) 2, 4 - dichlorophenoxy ester under the effects of catalyst hydrolysis reaction, to obtain 2, 4 - dichloro acid; said catalyst is selected from a polyether, a crown ether, quaternary ammonium salt, tertiary amine, [...], pyridine, titanate, inorganic acid, in organic acid one or more. The invention by halogenated acetate with 2, 4 - dichlorophen salt obtained by reaction of 2, 4 - dichlorophenoxy ester, and then in particular under the action of catalyst by hydrolysis reaction of the 2, 4 - dichloro acid. The invention specific reaction line combined with a specific catalyst such that the final preparation to obtain 2, 4 - dichlorophenoxyacetic acid purity and yield is relatively high, few by-products, the reaction route is simple, and is favorable for application.

Preparation method for 2,4-dichlorophenoxyacetic acid

The invention provides a preparation method for 2,4-dichlorophenoxyacetic acid, belonging to the technical field of organic synthesis. The preparation method comprises the following steps: a) reactinghalogenated acetate with 2,4-dichlorophenolate in the presence of a phase-transfer catalyst so as to obtain 2,4-dichlorophenoxyacetate; and b) hydrolyzing 2,4-dichlorophenoxyacetate so as to obtain 2,4-dichlorophenoxyacetic acid. According to the invention, oil-phase halogenated acetate reacts with 2,4-dichlorophenolate under the action of the phase-transfer catalyst to prepare 2,4-dichlorophenoxyacetate, and then 2,4-dichlorophenoxyacetate is hydrolyzed to obtain 2,4-dichlorophenoxyacetic acid and corresponding alcohols. Under the action of the phase-transfer catalyst, few hydrolysis by-products are produced during a reaction, fast reaction speed and high conversion rate and yield are obtained, and the amount of produced waste water is low; so industrial application of the preparation method can be easily implemented.
