Build ings types

UL 80, Steel Tanks for Oil-Burner Fuel, covers the design and construction of welded steel tanks of the atmospheric type with a maximum capacity of 0.23 to 2.5 m (60 to 660 gal) intended for unenclosed installation inside of buildings or for outside aboveground applications as permitted by the Standard for Installation of Oil-Bum-ing Equipment, NFPA 31, primarily for the storage and supply of fuel oil for oil burners. 

For the synthesis of organic compounds, two types of reaction are used C,C-bond-form-ing reactions for the construction of large structures from small units, and functional group interconversion for introduction of the functionality into the target molecule and for activation of the building blocks [44].
