The invention relates to an environmentally-friendly water-soluble non-oil metal rust-inhibiting lubricant which is characterized by comprising the following materials in percent by weight: 30% of amine borate, 5% of sodium gluconate, 2% of sodium molybdate, 20% of monoethanolamine, 13% of polyethylene glycol, 5% of ethanol, 15% of glycerol and the balance of deionized water. An organic metal corrosion inhibitor and an inorganic metal corrosion inhibitor are compounded and blended into the rust-inhibiting lubricant, thus the modern civilization production requirements for low energy consumption, low pollution, low emission and high environment friendliness are met. The lubricant has the four functions of inhibiting rust, removing rust, lubricating and washing and is a high-efficiency maintaining agent which is used for the production, storage, maintenance and repair of a variety of mechanical equipment, precision instruments and parts and component and can be used for keeping the metal product in the optimum work state so that the service life of the metal product is prolonged. The detection of the Shenyang Disease Control Center shows that the LD50 (lethal dose, 50%) is more than10,000mg/Kg, and the fishes and shrimps can live and propagate normally in 1 per mill aqueous solution.

A kind of method that nano-palladium catalyst catalyzes Suzuki coupling reaction to synthesize biphenyl compounds is to adopt the Suzuki of aryl tetrafluoroborate diazonium salt and aryl boric acid catalyzed by the nano-palladium catalyst that is easy to prepare, stable to water and air, and catalytic activity is high. Synthesis of biphenyl compounds by coupling reaction. The synthesis method has the characteristics of simple process, high reaction yield and the like.

[In the formula (I), Z represents a divalent group. A plurality of Y may be the same or different, and represent a monovalent boronate residue having at least one hydroxyl group, Ar¹ and Ar² may be the same or different, and represent a trivalent aromatic hydrocarbon group or a trivalent heterocyclic group.].

The invention relates to a boron-doped carbon quantum dot containing transition metal as well as a preparation method and application of the boron-doped carbon quantum dot. The preparation method comprises the following steps: mixing a nitrogen heterocyclic compound containing boric acid groups, iron salt and other transition metal compounds with a solvent, adding nitric acid and ethylenediamine, heating to 120-160 DEG C, reacting for 4-8 hours, carrying out solid-liquid separation, and freeze-drying the filtrate to finally obtain the carbon quantum dots capable of detecting the content of hydrogen peroxide and glucose in a sample through a colorimetric and fluorescent bimodal method. The method disclosed by the invention has a series of advantages of simple synthesis process, few types and quantity of required raw materials, low preparation cost, outstanding product performance and the like, and has a relatively good application prospect in the field of analysis and detection.
