Abstract:
The invention discloses a method for the continuous preparation of n-butyl nitrite with a low content of n-butanol comprising the reaction of n-butanol, an acid and NaNO 2  in a continuous way, in which the n-butanol, an acid and NaNO 2  are mixed in a mixing device which provides for a pressure drop of at least 1 bar; the acid is selected from the group consisting of HCI, H 2 SO 4 , formic acid, methanesulfonic acid, and mixtures thereof; and the amount of HCI is at least 1.02 molar equivalent based on the molar amount of n-butanol.

Claim (Index 8):
The method according to  claim 1 , wherein REAC1 is done in a loop shaped device LOOPDEV;\n n-Butanol, ACI and NaNO 2  are fed into LOOPDEV providing a reaction mixture REACMIX in LOOPDEV; LOOPDEV comprises MIXDEV and a device CONVDEV for conveyance of REACMIX; and the outlet of MIXDEV is connected to the inlet of CONVDEV and the outlet of CONVDEV is connected to the inlet of MIXDEV, thereby the loop is formed.
