This application relates to a low-alpha-ray silica and its preparation method. The method involves adding a high-purity sodium sulfate solution to water glass, followed by the sequential addition of dilute sulfuric acid solutions of varying concentrations for aging. The resulting precipitate is then calcined to obtain low-alpha-ray silica with Th ≤ 5 ppb and U ≤ 5 ppb. The sodium sulfate solution optimizes the precipitation process in two ways: first, it increases the ionic strength of the solution, compresses the colloidal double layer, and disrupts the metastable state of the system, thus promoting the aggregation and crystallization of the target precipitate; second, sulfate ions preferentially complex or inhibit the precipitation tendency of impurity cations based on the common ion effect; furthermore, the dilute sulfuric acid solution promotes the reaction and rapid precipitation of silicate ions with hydrogen ions, causing the Th and U ions encapsulated in the precipitate to precipitate out, thereby reducing the impurity content in the solution. This low-alpha-ray silica, due to its extremely low Th and U content and good thermal conductivity, can be widely used in high-performance and special-purpose chip packaging fields.

Film formation is then achieved using two different methods: spin coating and layer-by-layer self-assembly. In summary, this invention avoids the damage to the material structure caused by traditional ultrasonic exfoliation and the harm to the human body caused by the use of highly toxic organic solvents. Furthermore, the process is simple, and the method for preparing two-dimensional oxide nanosheets and thin films has a certain degree of universality. The film formation is controllable, and the prepared thin films can be applied to fields such as memristors and optoelectronic devices.

This invention relates to a method for synthesizing phenylhydrazine hydrochloride, belonging to the field of pharmaceutical synthesis technology. Using palladium chloride as a catalyst and sodium ethoxide as a basic agent, under conditions of 50-55°C, an oxidative addition reaction first occurs with the bromine atom on a haloaromatic compound with a bromine atom at the para position, increasing the oxidation state of palladium and forming a highly reactive palladium intermediate. Sodium ethoxide neutralizes the generated hydrogen bromide, driving the reaction forward. The lone pair electrons on the nitrogen atom in hydrazine hydrate attack the palladium intermediate, undergoing a nucleophilic substitution reaction, attaching the nitrogen atom to the carbon atom bonded to the bromine atom. The palladium intermediate then undergoes a reduction reaction, restoring the oxidation state of palladium and generating phenylhydrazine compounds. Simultaneously, palladium chloride is regenerated and can continue to participate in the catalytic cycle. Ethanol serves as the reaction solvent, providing a homogeneous environment for the reaction. Hydrochloric acid is then added to the reaction system, where hydrogen ions combine with the nitrogen atom in the phenylhydrazine molecule to form a stable salt.
