The PTI wood products are very well adapted for paint and stain applications with no bleed-through. The addition of the wax stabilizer allows a lower preservative retention plus substantially reduces the tendency of wood to warp and split as it dries. In combination with normal deck maintenance and sealer applications, the stabilizer helps ...
The heating (dry distilling) of wood causes tar and pitch to drip away from the wood and leave behind charcoal. Birchbark is used to make birch-tar, a particularly fine tar. The terms tar and pitch are often used interchangeably. However, pitch is considered more solid, while tar is more liquid.
Most diethyl ether is produced as a byproduct of the vapor-phase hydration of ethylene to make ethanol.This process uses solid-supported phosphoric acid catalysts and can be adjusted to make more ether if the need arises: [9] Vapor-phase dehydration of ethanol over some alumina catalysts can give diethyl ether yields of up to 95%.
Oil-varnish blends (i.e. Danish oil, Teak oil, [30] "Tung oil finish") Enhances natural figure like a drying oil, but more protective and faster drying. Low, but more than pure oil finishes. Fairly durable, but may require periodic reapplication for heavy use areas such as tables and worktops.
The main feedstock is vacuum gas oil, a heavy fraction of petroleum. [14] [15] The products of this process are saturated hydrocarbons; depending on the reaction conditions (temperature, pressure, catalyst activity) these products range from ethane, LPG to heavier hydrocarbons consisting mostly of isoparaffins.

Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound (a vicinal diol [7]) with the formula (CH 2 OH) 2. It is mainly used for two purposes: as a raw material in the manufacture of polyester fibers and for antifreeze formulations. It is an odorless, colorless, flammable, viscous liquid.
Monosubstituted products are formed by reacting a large excess of amine with ethylene oxide in presence of water and at a temperature below 100 °C (212 °F). Disubstituted products are obtained with a small excess of ethylene oxide, at a temperature of 120–140 °C (250–280 °F) and a pressure of 0.3–0.5 MPa (45–75 psi). [95] [96]
