Method for synthesizing diethylene glycol methyl hexyl ether

The invention discloses a method for synthesizing diethylene glycol methyl hexyl ether. The method comprises the following steps: (1) putting a raw material, namely sodium hydroxide, into a reaction kettle, adding a diluted hydrochloric acid solution into the reaction kettle slowly and dropwise and reacting to produce sodium chloride; (2) adding diethylene glycol monohexyl ether into the reaction kettle in the step (1) dropwise, and introducing the obtained sodium alcoholate intermediate product into the next level of reaction kettle; (3) coating the secondary reaction kettle, in which the sodium alceholate intermediate product is put, with a graphite layer, introducing methyl iodide into the secondary reaction kettle and reacting to obtain a final product, namely the diethylene glycol methyl hexyl ether; (4) after the reaction in the step (3), cooling to room temperature, standing and layering, and performing pressure-reducing filtration on the upper layer liquid to obtain the final product, namely the diethylene glycol methyl hexyl ether. The method has the advantages that the diethylene glycol methyl hexyl ether is synthesized by innovatively adopting the new raw material; the whole synthesis method is stable in reaction and easy to operate; the obtained final product has high yield and high purity; the method is suitable for industrialized production and breaks through bottleneck for commercial popularization of the products.

Special soldering tin paste used for welding multi-stage package patch element

The invention belongs to special soldering tin paste used for welding a multi-stage package patch element and particularly applicable to the occasion with the service temperature higher than 240 DEG Cafter welding. The special soldering tin paste comprises a tin alloy, nanometer metal, a rare earth alloy and soldering aid paste. Tin alloy powder is a mixture of one or two of tin silver alloy powder, tin antimony alloy powder, tin copper alloy powder and tin lead alloy powder. Nanometer metal powder is a mixture of one or two of copper powder, lead powder, titanium powder, cobalt powder and gold powder. Effective components of the soldering aid paste comprise hydrogenated rosin, diethylene glycol monohexyl ether, succinic acid, methyl-1H-benzotriazole and citric acid. A manufacturing method of the paste comprises a few steps of preparing the tin alloy powder, the nanometer metal powder, the rare earth alloy powder and the weld aid paste and mixing. By the adoption of the technical scheme, elementary-substance metal particles or alloy particles are added into the tin paste, corresponding nanometer auxiliary additives are added, thus the preparation cost is lower than that of nanometer soldering paste, and the special soldering tin paste is easy to achieve and wide in application range.
