Over the last two decades, the incidence of mouldy and musty off-flavours in cork-sealed wines has increased significantly. 2,4,6-Trichloroanisole (TCA) has been identified as the primary chemical responsible for cork taint. The human olfactometry threshold for TCA is 4–10 ng L−1 in white wine and 50 ng L−1 in red wine.
Chemical structure of 2,4,6-trichloroanisole (TCA), the compound primarily responsible for cork taint. Cork taint is a broad term referring to an off-odor and off-flavor wine fault [1] arising from the presence of 2,4,6-trichloroanisole (TCA), a chemical compound that represents one of the strongest off-flavors, and one "generated naturally in foods/beverages", in particular wines, that ...
Dibenzazepine derivatives are described in U.S. patent 3,074,931 issued 1963-01-22 by assignment to Smith Kline & French Laboratories. The compounds described share a tricyclic backbone different from the backbone of the TCA amitriptyline. Merck introduced the second member of the TCA family, amitriptyline (Elavil), in 1961. [60]
The ST-26 was intended to provide for crossing of trenches and streams 6–6.5 m (20–21 ft) wide and barriers up to 2 m (6.6 ft) high by T-27, T-26 and BT light tanks: the bridge had a maximum load rating of 14 tonnes (15 short tons). The bridge could be laid with the help of the cable winch in 25–40 seconds without crew exit; the raising ...
The planes collided 17 miles east of the LAX radar antennae, at 2,200 feet MSL, just below the floor of the TCA The IFR flights were required to remain within the confines of the Los Angeles Group 1 terminal control area (TCA) (now Class B Airspace ), while smaller planes were required to remain outside of the TCA, until the designated entry ...
Trans-Canada Air Lines (also known as TCA in English, and Trans-Canada in French) was a Canadian airline that operated as the country's flag carrier, [2] with corporate headquarters in Montreal, Quebec. [1] Its first president was Gordon Roy McGregor. Founded in 1937, [3] [4] it was renamed Air Canada in 1965.
TCA were unable to supply such a system, but nonetheless made a written offer to instead supply a different system rated at 5.39 liters per second, and attached to this quote were TCA's terms and conditions for this offer. Mechenex eventually accepted TCA's offer "as per TCA's quotation", and TCA manufactured and delivered the coils.
