Description
Technical field
The invention belongs to natural gas additive fields, and in particular to a kind of natural gas leaking foul smell additive and its preparation side
Method.
Background technique
Currently, in metal cutting field, main cutting gas to be applied has acetylene gas, propane flammable gas, oil liquefied gas and with third
Ingredient adds the gaseous mixture of other additives based on alkane.The advantages of acetylene gas is flame temperature height, and cutting speed is fast, the disadvantage is that high
Energy consumption, high pollution, high cost.With propane and based on propane ingredient plus other additives gaseous mixture, applied in market
In, although Costco Wholesale is cheaper than acetylene gas, ignition temperature is relatively low (2550 degree of -2900 degree), preheating, cutting speed
Slowly, the features such as cutting thickness is low, and density ratio air is big, and not volatile after leakage, there is certain safety in use
Hidden danger；Meanwhile natural gas leaking also be easy to cause security risk due to not noticeable, therefore, how constantly to improve natural gas
Safety in utilization be also the emphasis studied at present.
Summary of the invention

2%, tetrahydrofuran 5-7%, stink additive 0.1-0.2%, chloroplatinic acid 0.08-0.1%, remaining be C5-C7 isoparaffin.
The preparation method of the stink additive the following steps are included:
(1) cordate houttuynia for taking 30-40 parts by weight is added in the n-hexane of 3-4 times of its weight, stirs evenly, and increases temperature
Degree is 60-65 DEG C, and insulated and stirred 1-2 hours, filtering obtained extracting solution；
(2) said extracted liquid is taken, the dibutyl tin dilaurate of 0.1-0.3 parts by weight is added, it is 10-15 minutes ultrasonic, i.e.,
Obtain the stink additive.
A kind of preparation method of natural gas leaking foul smell additive, comprising the following steps:
(1) triethylamine is taken, is mixed with above-mentioned stink additive, insulated and stirred 1-2 hours at 46-50 DEG C, amination is obtained and adds
Add agent；
(2) chloroplatinic acid is taken, is added in tetrahydrofuran, is stirred evenly, is mixed with above-mentioned amination additive, is sent to 60-
In 65 DEG C of water bath with thermostatic control, insulated and stirred 20-30 minutes, discharging obtained tetrahydrofuran solution；
(3) above-mentioned tetrahydrofuran solution is taken, mixes, stirs evenly with remaining each raw material, through reaction kettle side after standing 2-3 hours
Bleeder valve clear liquid is released, pour into plastic barrel.
The additive amount of the natural gas leaking foul smell additive is the 1-1.5% of natural gas weight.
It compared with prior art, can be thorough the beneficial effects of the present invention are: natural gas motorcar of the invention is highly-safe
Burning, smoke dust and hydrogen sulfide, the feature of environmental protection is good, and tetrahydrofuran of addition etc. has the volatility of height, low toxicity, and mobility
Good, the present invention is also added into the organic extract of cordate houttuynia, the certain stink of natural gas is imparted, in this way, in natural gas leaking
When be easy to be noticeable, can effectively avoid it is living reduce explosion loss, improve safety in utilization.
