Acrylonitrile
It is used in the production of acrylic fibers, plastics, and rubbers.
Exposure to acrylonitrile can occur through inhalation, skin contact, or ingestion, and it has been shown to have toxic and carcinogenic effects.
Researchers studying acrylonitrile can leverage the power of PubCompare.ai, an AI-driven tool that helps efficiently locate optimal protocols from literature, pre-prints, and patents.
The tool enables AI-based comparisons to identify the most reliabel and accurate methods, enhancing reproducibility and precision in acrylonitrile studies.

The array of guide tubes is assembled by building up layers of polyimide tubes and fixing them with cyanoacrylate glue (see Supplementary Material). Electrodes can either be layered in an offset pattern with each layer resting in the grooves of the preceding layer, resulting in a “honeycomb” type pattern, or layered with no offset giving a rectangular pattern (Figure
The closest lateral spacing between electrodes that can be accomplished with this method is dictated by the outer diameter of the guide tubes. We recommend a distance of ~250 μm or larger for the guide tubes (using 33 gauge), but higher densities of ~125 μm are possible by using smaller diameter guide tubes. However, tests conducted with dense electrode arrays of pitches of 125 μm failed to yield usable recordings, possibly due to an increased inflammatory response.
The array of guide tubes is attached to a plastic drive body (Figures

Example 2
A dispersion comprising 242 parts of water, 30.7 parts of 50 wt. % surface-modified colloidal silica (Bindzil, 80 m2/g, particle size 32 nm surface-modified with 50% propylsilyl/50% glycerolpropylsilyl) was prepared and maintained at a pH of about 4.5. The aqueous dispersion was mixed with an organic phase that contained 2.0 parts of dilauroyl peroxide, 27 parts of isopentane and 0.3 parts of trimethylolpropane trimethacrylate. Acrylonitrile (AN) and α-methylene-γ-valerolactone (MVL) were added in the amounts as indicated in Table 1. Polymerization was performed at 62° C. in a sealed reactor under agitation during 20 hours. After cooling to room temperature a sample of the obtained microsphere slurry was removed for determination of the particle size distribution. After filtration, washing and drying the particles were analyzed by TMA. The dry particles contained about 19 wt. % of isopentane. The TMA-results and particle sizes are found in Table 1.
Example 7
A reaction mixture containing Mg(OH)2-stabilised organic droplets in water was created by mixing the phases and stirring vigorously until a suitable droplet size had been achieved. The water dispersion contained 6.5 parts of Mg(OH)2 and 221 parts of water. The organic droplets contained 0.52 parts of di(4-tert-butylcyclohexyl) peroxydicarbonate, 34 parts of isopentane and 0.3 parts of trimethylolpropane trimethacrylate. Acrylonitrile (AN), α-methylene-γ-valerolactone (MVL) and methyl methacrylate (MMA) were added in the amounts as indicated in Table 2 in parts per weight. Polymerization was performed in a sealed reactor under agitation at 56° C. during 6 hours followed by 62° C. during 5 hours. After cooling to room temperature a sample of the obtained microsphere slurry was removed for determination of the particle size distribution. After filtration, washing and drying the particles were analyzed by TMA. The dry particles contained about 25 wt. % of isopentane and had a median particle size of about 26 μm. The TMA-results are found in Table 2.
Example 25
A dispersion comprising 246 parts of water, 26.8 parts of 50 wt. % surface-modified colloidal silica (Levasil, particle size 60 nm surface-modified with 40% propylsilyl/60% glycerolpropylsilyl) was prepared and maintained at a pH of approx. 4.5. The aqueous dispersion was mixed with an organic phase that contained 2.0 parts of dilauroyl peroxide, 27 parts of isopentane and 0.3 parts of trimethylolpropane trimethacrylate. Acrylonitrile (AN) and α-methylene-γ-butyrolactone (MBL) were added in the amounts as indicated in Table 5. Polymerization was performed at 62° C. in a sealed reactor under agitation during 20 hours. After cooling to room temperature a sample of the obtained microsphere slurry was removed for determination of the particle size distribution. After filtration, washing and drying the particles were analysed by TMA. The dry particles contained about 17 wt. % of isopentane. The TMA-results and particle sizes are found in Table 5.
