Abstract

The invention discloses a glyphosate assistant and a preparation method thereof. The glyphosate assistant comprises the following raw materials in percentage by weight: 15-30% of anhydrous sodium sulfite, 10-15% of sulphamic acid or sodium borate, 40-60% of ammonium bicarbonate, 5-10% of catalyst and 4-15% of surfactant; the glyphosate assistant can convert glyphosate active compound into glyphosate soluble powder under the condition of normal temperature and normal pressure; the prepared soluble powder is dry, and the expanding or moisture absorption is avoided; the preparation method mainly comprises the steps of preparing surfactant, catalyst and product; and the preparation method is simple and practicable.

Description

technical field [0001] The invention relates to a chemical auxiliary agent, in particular to an auxiliary agent for converting glyphosate original drug into water-soluble glyphosate soluble powder and a preparation method thereof. Background technique [0002] Glyphosate is the pesticide variety with the largest production and sales in the world. It is a herbicide with broad spectrum, high efficiency, low toxicity and excellent environmental compatibility. It is widely used in orchards, vegetable gardens, rubber gardens, non-arable land and crop sowing No tillage and weeding before or after harvest. After the promotion of glyphosate-resistant genetically modified crops, a wider market has been opened up for glyphosate. Due to the poor solubility of the original glyphosate, the common way to solve the problem is to convert it into ammonium glyphosate, [0003] There are two general production methods: one is to use glyphosate raw powder and ammonia gas, liquid ammonia or am...
