The invention discloses epoxy polyester resin, an epoxy polyester resin preparation method and a powder coating composition with the epoxy polyester resin. The epoxy polyester resin is prepared by steps: polymerizing main materials including terephthalic acid, fumaric acid, dodecenylsuccinic acid, ricinoleic acid, neopentyl glycol, 1,2,4-cyclohexane monoallyl tricarboxylate, 4-pentenol and the like, and subjecting a polymer to epoxidation reaction under the action of an oxidant. The epoxy polyester resin is capable of completely substituting E-12 epoxy resin for curing with commercially available 5:5 high-acid-value carboxyl polyester, and low consumption and low cost are realized.

The invention provides a scale-inhibiting and antibacterial material and a preparation method thereof, and the scale-inhibiting and antibacterial material comprises the following components in percentage by weight: 75-85% of a scale-inhibiting material, 5-10% of an antibacterial material and 5-20% of a binder, the scale inhibition material is at least two of polyaspartic acid salt, polyepoxysuccinic acid salt, 1-hydroxyethylidene-1, 1-diphosphonate, phosphono butane tricarboxylate and a phosphono carboxylate copolymer. The synergistic compounding effect of two or more scale inhibition materials is adopted, so that the scale inhibition effect is better than that of a single scale inhibition material. The scale-inhibiting antibacterial material, an antibacterial material, a binder and activated carbon powder are prepared into an activated carbon rod with a water purification effect, the activated carbon rod can be applied under the complex water quality condition, the service life of the activated carbon rod can be prolonged, and compared with the activated carbon rod with the water purification effect, which is directly prepared from the scale-inhibiting antibacterial material, the antibacterial material, the binder and the activated carbon powder, the service life of the activated carbon rod is prolonged. The scale inhibitor has better scale inhibition and antibacterial effects.

The invention relates to a liquid hard surface cleaning and disinfection composition. The present inventors have found that inclusion of benzalkoniuim chloride and selected salts of di or tricarboxylic acid when combined with thymol or terpineol provides synergistic antimicrobial action in a rapid fashion and such efficacy is obtained at very low concentrations of thymol and / or terpineol.

Provided are resin compositions with favorable melt fluidity, sliding characteristics, toughness, and mechanical strength. The resin compositions comprise an aromatic polyamide imide resin (A) that is obtained with the moisture content in the reaction system at 100 to 5000 ppm during the reaction to polymerize an aromatic tricarboxylate anhydride and a diisocyanate and for which the reduced viscosity in N, N-dimethyl acetamide at 30 DEG C is 0.15 to 0.40 dl / g, and a polyarylene sulfide resin (B).

The invention relates to a concentrated phosphoric acid anti-deposition agent which comprises the following components in parts by weight: 8-10 parts of amino trimethylene phosphoric acid, 3-5 parts of phosphonocarboxylic acid, 17-33 parts of a first acrylic acid multi-element copolymerized isopolymer, 33-42 parts of a second acrylic acid multi-element copolymerized isopolymer, 6-10 parts of 2-phosphono-1, 2, 4-butane tricarboxylate, and 30-40 parts of polymaleic anhydride. The anti-deposition agent containing a surfactant and organic active substances can generate a certain inhibition effecton nucleation and crystallization of potassium fluosilicate and sodium fluosilicate, and the scale inhibition rate in a laboratory can reach 80% or above; and the effect of the industrial test is good. Therefore, by selecting the additive, scaling can be effectively slowed down, and scaled substances are loosened, so that the start-up rate of a wet-process phosphoric acid filtering system is favorably improved, the scaled substance cleaning time is shortened, the purposes of increasing the yield and reducing the consumption are achieved, and the application and popularization values are great.

A 4,5-disubstituted-1H-pyrrolo(2,3-f)quinolin-2,7,9-tricarboxylate compound, or an analog, or derivative thereof, having a structure of Formula I:R1 and R4 are each independently an atom or group selected from hydrogen, a linear or branched C1-8 alkyl group, a deuterated linear or branched C1-8 alkyl group, an aralkyl group, or a substituted aryl group; R2 is independently an atom or group selected from halogens, a linear or branched C1-8 alkoxy group, or a deuterated linear or branched C1-8 alkoxy group; and R3 is independently an atom or group selected from a linear or branched C1-8 alkoxy group, or a deuterated linear or branched C1-8 alkoxy group. The compound is useful as a reaction intermediate for the synthesis of PQQ. A process in which CAN is used as an oxidant in the synthesis of PQQ in existing patents and literatures is replaced. This makes the process cheaper and more efficient.
