Embodiment 1

[0017] Embodiment 1: this potassium humate obtains by following preparation method: the first step, tert-butyl peroxyneodecanoate waste liquid is separated, obtains aqueous phase solution after separation; Second step, takes by weight parts 120 to 180 parts of phase solution, 75 to 90 parts of weathered coal powder, and 100 to 180 parts of deionized water. Mix the required amount of aqueous phase solution, weathered coal powder and deionized water evenly to obtain a mixed solution; The third step is to heat the mixed solution to 75°C to 90°C for reaction, test the pH value of the mixed solution during the reaction, and obtain a dark brown paste after the reaction. The fourth step is to dry the dark brown paste The dried substance of potassium humate is obtained, wherein: the reaction time is 50 minutes to 70 minutes, the pH value at the end of the reaction is 9 to 11, the drying temperature is 85°C to 110°C, and the drying time is 3 hours to 5 hours.

Embodiment 2

[0018] Embodiment 2: this potassium humate obtains by following preparation method: the first step, tert-butyl peroxyneodecanoate waste liquid is separated, obtains aqueous phase solution after separation; Second step, takes by weight parts 120 or 180 parts of phase solution, 75 or 100 parts of weathered coal powder, 90 or 170 parts of deionized water, and mix the required amount of water phase solution, weathered coal powder and deionized water to obtain a mixed solution; The third step is to heat the mixed solution to 80°C or 100°C for reaction, test the pH value of the mixed solution during the reaction, and obtain a dark brown paste after the reaction. The fourth step is to dry the dark brown paste To obtain dried potassium humate, wherein: the reaction time is 40 minutes or 90 minutes, the pH value at the end of the reaction is 9 to 11, the drying temperature is 90°C or 120°C, and the drying time is 3 hours or 5 hours.

Embodiment 3

[0019] Embodiment 3: As the optimization of the foregoing examples, the waste liquid of tert-butyl peroxyneodecanoate contains 10% to 15% of potassium hydroxide and 3% to 5% of tert-butyl peroxide potassium.

Abstract

The invention relates to potassium humate and a preparation process thereof. The potassium humate is obtained by the method comprising the following steps: first step, separating tert-butyl peroxyneodecanoate waste liquor to obtain a water-phase solution; second step, weighing the water-phase solution, weathering pulverized coal and deionized water in parts by weight, and uniformly mixing to obtain a mixed solution; third step, heating and reacting the mixed solution to obtain dark brown paste; and fourth step, drying the dark brown paste to obtain dried potassium humate. The potassium humateis prepared from potassium hydroxide and potassium tert-butyl peroxide in the tert-butyl peroxyneodecanoate waste liquor and humic acid in the weathering pulverized coal, the potassium hydroxide and the potassium tert-butyl peroxide in the tert-butyl peroxyneodecanoate waste liquor are utilized effectively, costs for treatment of the tert-butyl peroxyneodecanoate waste liquor are avoided, and furthermore, the potassium humate with economic benefit is obtained.

Description

technical field [0001] The invention relates to potassium humate and a preparation method thereof. Background technique [0002] In the process of synthesizing PVC polymerization initiator tert-butyl peroxyneodecanoate, after extracting the oil phase product, the remaining water phase contains excess unreacted potassium hydroxide, tert-butyl potassium peroxide and by-product chlorine Potassium chloride, the remaining aqueous phase is collected as tert-butyl peroxyneodecanoate waste liquid at present and then sent to the sewage treatment station for centralized treatment, which not only increases the treatment cost, but also wastes the potassium resources that are in short supply in the market. Contents of the invention [0003] The invention provides potassium humate and a preparation process thereof, which overcomes the above-mentioned deficiencies in the prior art, and can effectively solve the problem that potassium resources in tert-butyl peroxyneodecanoate waste liqui...
