The Jj method from steam is effective, requires a catalyst of 0 atmospheres, oxidation 514-oxidation; BHIHH yarn. For the synthesis of porn, aldehydes and formic acid, it is necessary to pass through one more stage, the culm. This type of synthesis method cannot be expected to develop in the future due to energy consumption, soil conditions, and operating costs. However, in 20 to 30 years, when the depletion of stone t111 becomes a problem, cheap formaldehyde, formic acid, and methanol (jl1) will be used to secure food and fuel.
