  • Patent number: 4546206
    Abstract: Methyl t-butyl ether and methyl t-amyl ether are produced by reacting methanol with isobutene and isoamylene, respectively, at a total methanol/isoolefine mole ratio of 1-1.2:1 in a series of reaction stages such that in the first reaction stage, the total amount of olefin component is reacted with as much methanol as is required to ensure that the methanol/isoolefine mole ratio in the first reaction stage does not drop to less than 0.65:1, and that the methanol concentration in the effluent stream does not exceed 0.4% wt. The residual amount of methanol is then fed either all at once to another reaction stage, or in portions to several additional reaction stages.

  • Patent number: 4526907
    Abstract: When producing molded foam parts from liquid reaction components, the charge of gas in the initial components has a significant effect on the foam structure and quality of the molded part. This invention provides a process and apparatus for introducing a gas into at least one of the liquid reaction components prior to mixing said components for reaction. The component which is to be charged with gas is circulated from a feed tank through a recycle circuit to a compression zone which is maintained at a higher pressure than that of the feed tank. Said gas is admixed with said component at the point of initiation of the compression zone and the higher pressure is relieved through a throttle element prior to returning the gas-charged component to the feed tank. A finely divided stable gas dispersion which can be mixed with other components for reaction is obtained.

  • Patent number: 4486102
    Abstract: A mixing head for multicomponent plastics, especially polyurethane, in whose mixing chamber (2) a hollow piston (7) can be moved to and fro to control the component streams. The hollow piston contains an expulsion piston (8), which is movable independently of the hollow piston, and which can be passed through an outlet tube (3) which adjoins the outlet orifice (4). The end face (12) of the hollow piston forms, together with the mixing chamber wall (11) nearest the sprue, a shearing gap in which the components are mixed. As a result of the design and arrangement of the pistons (7) and (8), good mixing is achievable even under critical conditions, and the mixing chamber is also easily cleaned.
