Embodiment 1

[0043] It is weighed with diisopropylamine 20.2 g (0.2 mol), dissolved in 40 ml of acetonitrile, and 1-bromopropane 12.2 g (0.1 mol) was dissolved in 30 mL of acetonitrile, and the two solutions were mixed after mixing for 72 hours, and gradually had a white solid. generate. Cooled to room temperature, 50 mL of distilled water was added, and the reaction liquid was divided into two layers. The upper liquid, 30 ml distilled water was separated twice with a separatory funnel. The product yield is increased by nearly 9 times (compared to the contrast 1), and the ammonium salt generated as the precipitation is deposited, and can be collected by simple filtration, which is more suitable for production.

Embodiment 2

[0045] It is called diisopropylamine (1.43 g, 10 mmol), dissolved in 20 mL of ethanol, stirring with HBF. 4 The solution was about 2 ml to weak acid (pH ≈ 6), allowed for a few minutes, filtration, filtrate, and purified colored colored crystals were precipitated after about two days.

Embodiment 3

[0047]The powder sample of the compound diisopropylamine tetrafluoroborate crystal is pressed into a sheet shape having a thickness of about 0.6 mm, electrode, copper wire, carbon conductive gel, and measures the area of ​​carbon conductive glue on the electrode and The thickness of the electrode is then placed on a dielectric measuring instrument to determine data corresponding to temperature change; Nonlinear optical effect testing Nd: YAG pulsed laser beam of 1064 nm; in the Rigaku DSC8230 instrument The thermal measurement, the specific test conditions are under a nitrogen atmosphere, and the heating or cooling rate of 10 k / min is carried out in the aluminum crucible; the crystal structure is parsed by direct method, and the OLEX2.13 software package is based on F 2 Full matrix method intensive.
