Abstract: The subject invention pertains to an apparatus with the continuous expansion of thermoplastic minipellets, particularly polypropylene. The apparatus comprises a mixing means for mixing the thermoplastic minipellets in water to form a slurry, which is connected to a pressurizing means to form a flow of pressurized slurry to a junction which in trains a blowing agent to form a pressurized slurry mixture, which is connected to a heating means to heat the pressurized slurry mixture. Once the pressurized slurry mixture is impregnated with the blowing agent, it flows through water more orifice plates for expansion of thermoplastic minipellets into an expansion vessel.

Abstract: The subject invention pertains to a continuous process for expanding thermoplastic minipellets, particularly polypropylene. The minipellets are continuously expanded by continuously charging and mixing water and minipellets in a slurry tank to form a slurry which is subsequently pressurized. A blowing agent such as butane is entrained into the pressurized slurry flow, which said slurry is then heated by a heating means, such as a shell and tube heat exchanger, to the softening point of the minipellets. The heated minipellets are given the time necessary for impregnation by permitting them to flow through one or more impregnation vessels. The impregnated minipellets are released through an orifice into an expansion vessel where the blowing agent flashes off, thereby expanding the minipellets.

Abstract: The subject invention relates to herbicidal compositions comprising a dinitroaniline compound and a freezing point depressant compound selected from the group consisting of butyrolactone, N,N-dimethylformamide, and mixtures thereof.The compositions described herein are used as preemergent herbicides and are particularly useful in the control of grasses and broad-leaf weeds for crops such as cotton, soy beans, and peanuts. The freezing point of the dinitroaniline compound is lowered by the addition of the freezing point depressant additive without having a detrimental effect on the activity of the dinitroaniline, the crop, or the environment.

Abstract: A method of removing tetranitromethane from waste gases (e.g., from trinitrotoluene plants) by scrubbing the waste gases with a mixture of 1 an alkali metal hydroxide, 2 water, and 3 a liquid alcohol. Most of the tetranitromethane is converted into a soluble alkali metal salt of trinitromethane.

Abstract: A method of removing tetranitromethane from waste gases (e.g., from trinitrotoluene plants) by scrubbing the waste gases with a solution of (1) water, (2) hydrogen peroxide, and (3) an alkali metal hydroxide or alkali metal carbonate. Tetranitromethane is converted into trinitromethane or a soluble alkali metal salt of trinitromethane.
