2, but the raw materials used phosphorous acid price of this method is expensive, and the cost height is unfavorable for large-scale production, is difficult to popularization and application, and therefore, its innovation is imperative.
Three, summary of the invention
At above-mentioned situation; the present invention's purpose just provides a kind of bleach boosters and preparation method thereof; can effectively overcome bleach boosters price height; the problem that is difficult for large-scale production and is difficult to penetration and promotion; the technical scheme of its solution is; this bleach boosters KYLIN185 is by deionized water 144kg; diethylenetriamine 103kg; formaldehyde 405kg; phosphorus chloride 682kg; caustic soda 400kg; diethylene triamine pentacetic acid (DTPA) five sodium saturated solution 955kg make; its production method is with deionized water; diethylenetriamine; formaldehyde places the reactor stirring reaction; cooling is below 30 ℃; slowly drip phosphorus chloride; temperature in the kettle is no more than 40 ℃; the HCl gas water that reaction generates absorbs; afterwards; the gained material is warming up to 100 ℃ in the still; keep and refluxed 3 hours; be cooled to again below 50 ℃; be neutralized to pH7.5 with NaOH; material is cooled to below 40 ℃; off-response still valve; take out the material in the reactor; add diethylene triamine pentacetic acid (DTPA) five sodium saturated solution 955kg again, the mixing packing promptly gets product of the present invention.
Because of being to develop voluntarily,,, as follows so product of the present invention claims bleach boosters KYLIN185 again for being different from existing bleach boosters.
The present invention easily produces, cost is low, and material can fully utilize, and environmental protection is easy to produce and apply, and economic and social benefit is huge.
Four, description of drawings
Accompanying drawing is an apparatus and process flow chart of the present invention.
Five, the specific embodiment
Provide by technical scheme, the present invention is made by deionized water 144kg, diethylenetriamine 103kg, formaldehyde 405kg, phosphorus chloride 682kg, caustic soda 400kg, diethylene triamine pentacetic acid (DTPA) five sodium saturated solutions (being called for short the DTPA-5Na saturated solution) 955kg, wherein deionized water is that industrial deionized water (has cationic water and anionic water, be preferably cationic water), phosphorus chloride is the chloride of phosphorus, and phosphorus pentachloride (PCL is arranged
5) and phosphorus trichloride (PCL
3), meet all violent hydrolysis of water, be the chlorinating agent in the organic synthesis, preferably adopt phosphorus trichloride among the present invention, its phosphorus trichloride purity 〉=99.5%, diethylenetriamine claims diethylenetriamines again, its purity is 〉=99.5%; Caustic soda claims caustic soda again, caustic soda, i.e. NaOH (NaOH), its purity 〉=99.9% (ionic membrane caustic soda); Formaldehyde belongs to organic aldehyde, and its purity is 37%; More than said purity promptly be meant mass content (or claim mass concentration percentage number).Above-mentioned each component is the commercially available prod, and wherein diethylene triamine pentacetic acid (DTPA) five sodium are Changzhou chemical industry Co., Ltd product.
Product of the present invention, its production method is provided by accompanying drawing, shown in accompanying drawing, is realized by following steps:
1, cleaning reaction still 4 at first, and confirm that each valve open and close of reactor is errorless;
2, by the component metering, with deionized water, diethylenetriamine, stir in the formaldehyde material adding reactor, open reacting kettle jacketing condensed water water intaking valve 12, condensed water outlet valve 10, with the deionized water in it, diethylenetriamine and formaldehyde mixture material temperature are reduced to below 30 ℃, open the circulating pump 6 of spray absorber 5 again, drip jar 1 phosphorus chloride that in reactor, adds by the component metering by phosphorus chloride, little bleeder valve that opens, slowly drip phosphorus chloride, temperature of charge must not surpass 40 ℃ in the still, and simultaneously, the HCL gas that produces in the reaction is absorbed by the water that sprays in the absorption tower, enter the sour pond 8 of absorption, do his and use;
3, after phosphorus chloride drips, close condensed water water intaking valve 12 and condensed water outlet valve 10, open water-in and water-out valve and the steam inlet valve 11 and steam outlet valve 9 of condenser 3, make the surplus reacted material that goes in the reactor behind the HCL gas be warming up to 110 ℃ gradually, circulating valve 13 on the open cold condenser 3 makes the interior material vaporization of still, condensing reflux 3 hours;
