* Air Liquide sees 2013 net profit rising
* Air Liquide H1 profit down 4 percent on one-off costs
* Linde Q2 operating profit up 14.5 percent
* Both companies bolstered by healthcare acquisitions
FRANKFURT, July 30 (Reuters) - France's Air Liquide and Germany's Linde, the world's two biggest industrial gases producers, saw their strategy of expanding their healthcare businesses pay off in the second quarter.
Air Liquide said on Tuesday it expects full-year net profit to rise "barring a degradation of the environment" after restructuring costs caused a 4 percent decline in first-half profit to 752 million euros ($997 million).
In the second quarter alone, revenues at its Healthcare business, which accounts for 16 percent of group sales, jumped about 14 percent thanks to the acquisitions of French provider LVL Medical and Gasmedi in Spain as well as a rise in the number of home healthcare patients.
Linde meanwhile reported a 14.5 percent gain in quarterly operating profit to 1.01 billion euros ($1.34 billion), compared with consensus of 999 million euros in a Reuters poll, thanks to the acquisitions of U.S.-based Lincare and rival Air Products' European homecare business.
Linde said it was still aiming for an increase in sales this year and operating profit of at least 4 billion euros thanks to the expected earnings contribution from Lincare.
