    摘要： Infinitely water soluble, storage stable, low molecular weight, amine-modified resins/binders (e.g., phenol-formaldehyde resole resins and binders made therefrom) are used to produce low odor fiberglass products, such as fiberglass insulation for automobile headliners and room dividers. The cured, bonded fiberglass products have low TMA (trimethylamine) emission because the free formaldehyde in the resin has been scavenged with melamine, which resists thermal decomposition, and because the binder contains a relatively low urea content, which is a TMA contributor. The resole resin production process includes adding two different formaldehyde scavengers (e.g., melamine and urea) to produce a modified phenol-formaldehyde resole resin. This resole resin is produced into a binder by mixing with water, optionally in the presence of a latent acid catalyst (e.g., an ammonium salt of a strong acid). The binder can be applied to a fiberglass base material, dried, stored for an extended time period, and then cured and shaped into a final desired shape.

    摘要： A phenol-formaldehyde resole resin is combined with an ammonia-based formaldehyde scavenger to produce a product useful, for example, as a binder used in the production of glass fiber insulation products. The starting resin may have a free formaldehyde content of 1.5 to 14 wt. %, based on a total weight of the resin, and the resin and scavenger may be combined at a molar ratio in the range of 0.1 to 5. The resulting binder may have a free formaldehyde content of 1 wt. % or less, based on a total weight of the reaction product. This binder may then be applied to a glass fiber base material in a conventional manner.

    摘要： A method is disclosed for producing fluoronitrobenzene compounds by reacting chloronitrobenzene compounds with a fluoride salt in the presence of a tetramethylammonium salt phase-transfer catalyst. This catalyst allows the use of elevated reaction temperatures with substantial freedom from catalyst inactivation, resulting in yields and reaction rates which are improved over those of previously known methods using higher molecular weight quaternary ammonium salt phase transfer catalysts having more total carbon atoms in their ammonium cations.

    摘要： A method for producing fluoronitrobenzene compounds by reacting chloronitrobenzene compounds with a fluoride salt in the presence of a quaternary ammonium salt phase-transfer catalyst, wherein the catalyst is added to the reaction mixture incrementally during the course of the reaction. The incremental addition of catalyst allows the use of elevated reaction temperatures which, although sometimes causing catalyst inactivation, result in yields and reaction rates which are improved over those of methods involving a single catalyst addition.
