以氯化苄和2-甲基-4-硝基苯胺为原料，在较新的化学环境中，采用实验室合成工艺合成了有机非线性光学化合物N-苄基-2-甲基-4-硝基苯胺（BNA）。合成的BNA化合物通过使用石油醚的低压硅胶柱色谱（CC）分离，并且通过薄层色谱（TLC）确认分离的所得产物的纯度。此外，将该材料在甲醇中重结晶至少四次，并将高度纯化的BNA用于在室温下通过缓慢蒸发法从具有选定溶剂的溶液中生长单晶。收获具有自然生长形态的单晶，并通过光学测角法鉴定它们的不同生长面。生长的晶体进行了不同的表征技术，如粉末X射线衍射（PXRD），傅立叶变换红外光谱（FTIR），差示扫描量热法（DSC）和紫外可见近红外光谱。利用Kurtz和佩里粉末技术，以Nd：YAG激光为基本光源，研究了BNA晶体的倍频效率，发现其倍频效率是无机标准KDP的两倍。
Synthesis of the organic nonlinear optical compound N-benzyl-2-methyl-4-nitroaniline (BNA) was carried out in a newer chemical environment using the mixture of benzyl chloride and 2-methl-4-nitroaniline by a preferred laboratory synthesis process. The synthesized BNA compound was separated by column chromatography (CC) with low pressure silica gell using petrollium benzine and purity of the separated resultant product was confirmed by thin layer chromatography (TLC). Further, the material was recrystallized atleast four times in methanol and the highly purified BNA was used for the growth of single crystals from solutions with selected solvents by slow evaporation method at room temperature. Single crystals having natural growth morphology were harvested and their different growth faces were identified by optical goniometry. The grown crystals were subjected to different characterization techniques such as powder x-ray diffraction (PXRD), fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC) and UV–vis–Near IR spectroscopy. Further, the second harmonic generation (SHG) efficiency of the grown BNA crystal was studied by Kurtz and Perry powder technique using Nd:YAG laser as fundamental source and found to be twice that of inorganic standard KDP.
